Detection of Adriamycin-DNA adducts by accelerator mass spectrometry at clinically relevant Adriamycin concentrations<...
TY - JOUR. T1 - Detection of Adriamycin-DNA adducts by accelerator mass spectrometry at clinically relevant Adriamycin concentrations. AU - Coldwell, Kate E.. AU - Cutts, Suzanne M.. AU - Ognibene, Ted J.. AU - Henderson, Paul. AU - Phillips, Don R.. PY - 2008. Y1 - 2008. N2 - Limited sensitivity of existing assays has prevented investigation of whether Adriamycin-DNA adducts are involved in the anti-tumour potential of Adriamycin. Previous detection has achieved a sensitivity of a few Adriamycin-DNA adducts/104 bp DNA, but has required the use of supra-clinical drug concentrations. This work sought to measure Adriamycin-DNA adducts at sub-micromolar doses using accelerator mass spectrometry (AMS), a technique with origins in geochemistry for radiocarbon dating. We have used conditions previously validated (by less sensitive decay counting) to extract [14C]Adriamycin-DNA adducts from cells and adapted the methodology to AMS detection. Here we show the first direct evidence of Adriamycin-DNA ...

Particle accelerator - Wikipedia
A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to nearly light speed and to contain them in well-defined beams. Large accelerators are used in particle physics as colliders (e.g., the LHC at CERN, KEKB at KEK in Japan, RHIC at Brookhaven National Laboratory, and Tevatron at Fermilab), or as synchrotron light sources for the study of condensed matter physics. Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncological purposes, radioisotope production for medical diagnostics, ion implanters for manufacture of semiconductors, and accelerator mass spectrometers for measurements of rare isotopes such as radiocarbon. There are currently more than 30,000 accelerators in operation around the world. There are two basic classes of accelerators: electrostatic and electrodynamic (or electromagnetic) accelerators. Electrostatic accelerators use static electric fields to accelerate particles. The most ...
Evaporation of phosphorus in molten silicon by an electron beam irradiation method<...
TY - JOUR. T1 - Evaporation of phosphorus in molten silicon by an electron beam irradiation method. AU - Hanazawa, Kazuhiro. AU - Yuge, Noriyoshi. AU - Kato, Yoshiei. PY - 2004/3. Y1 - 2004/3. N2 - The evaporation behavior of phosphorus in molten silicon during electron beam irradiation was investigated with the aim of producing solar grade silicon (SOG-Si) from metallurgical grade silicon (MG-Si) by a sequential metallurgical process. Batch experiments showed that the evaporation rate of phosphorus increased in proportion to the power of the electron beam and phosphorus content. The phosphorus removal rate was controlled by free evaporation from the molten silicon surface. Electron beam irradiation makes it possible to secure a higher temperature at the free liquid surface, which results in more efficient dephosphorization. A continuous flow experiment indicated that the phosphorus concentration at the outlet increased when the silicon feed rate was raised, which was attributed to the fact that ...

Bending of metal-filled carbon nanotube under electron beam irradiation - [email protected]
Electron beam irradiation induced, bending of Iron filled, multiwalled carbon nanotubes is reported. Bending of both the carbon nanotube and the Iron contained within the core was achieved using two approaches with the aid of a high resolution electron microscope (HRTEM). In the first approach, bending of the nanotube structure results in response to the irradiation of a pristine kink defect site, while in the second approach, disordered sites induce bending by focusing the electron beam on the graphite walls. The HRTEM based in situ observations demonstrate the potential for using electron beam irradiation to investigate and manipulate the physical properties of confined nanoscale structures.

36Cl accelerator mass spectrometry with a bespoke instrument - Enlighten: Publications
Cosmogenic 36Cl analysis by accelerator mass spectrometry (AMS) is a valuable environmental and geological sciences research tool. Overcoming the stable nuclide 36S isobar interfering with measurement is challenging, however. Traditionally this has required large accelerators, but following recent technical advances it is now possible with 3C30 MeV ion energies. Consequently 5 MV or even smaller modern bespoke spectrometers are now 36Cl-capable, increasing accessibility and promoting wider and more varied 36Cl use. However, the technical ability to identify 36Cl ions is quite distinct from demonstrated high-performance AMS. Such is the theme of this paper. We present a systematic analysis of the accurate measurement of sample radioisotope relative to the stable chlorine, the normalisation of the measured ratio and correction for remaining 36S interference, all combined with the use of stable-isotope dilution to determine sample Cl concentration to begin with. We conclude by showing that ...

STT-MRAM
In this paper, we demonstrate the design of efficient and high-performance AI/Deep Learning accelerators with customized STT-MRAM and a reconfigurable core. Based on model-driven detailed design space exploration, we present the design methodology of an innovative scratchpad-assisted on-chip STT-MRAM based buffer system for high-performance accelerators. Using analytically derived expression of memory occupancy time of AI model weights and activation maps, the volatility of STT-MRAM is adjusted with process and temperature variation aware scaling of thermal stability factor to optimize the retention time, energy, read/write latency, and area of STT-MRAM. From the analysis of modern AI workloads and accelerator implementation in 14nm technology, we verify the efficacy of our designed AI accelerator with STT-MRAM STT-AI. Compared to an SRAM-based implementation, the STT-AI accelerator achieves 75% area and 3% power savings at iso-accuracy. Furthermore, with a relaxed bit error rate and negligible ...

Leicester Research Archive: The trace detection of DNA adducts by accelerator mass spectrometry and 14C-postlabelling
Accelerator mass spectrometry (AMS) is currently the most sensitive method for trace DNA adduct detection. O6-Mehtyldeoxyguanosine (O 6-MedG) is a strongly mutagenic lesion formed by a variety of alkylating agents. For this reason this was the adduct of choice for use in this study, the aim of which was to develop a 14C-postlabelling technique, involving incorporation of radiolabel onto O6-MedG adducts after isolation, thus enabling exploitation of AMS to detect low levels of adducts without the need to administer a 14C-labelled compound. A method was developed and optimised for acetylating O6-MedG, in , 90% yields. This method was then used to acetylate the adduct with 14C-acetic anhydride, but changes required for the safe handling of radiolabelled compound altered the reaction product profile, resulting in the major derivative being 14C-di-acetyl O6-MedG, (38% yield). This pure standard was used to determine detection limits of 1.4 pmoles of adduct using HPLC and liquid scintillation counting ...

Accelerator mass spectrometry (AMS) is an ultra-sensitive method to monitor and trace the environmental exposure levels of 14C-labeled molecules in vivo. Nicotine [3-(1-methyl-2-pyrrolidinyl)-pyridine], a major alkaloid in tobacco products, has proven to be a potential genotoxic compound. Using 14C-labeled nicotine and AMS, we have investigated the inhibitory effect of curcumin, garlic squeeze, grapeseed extract, tea polyphenols, vitamin C and vitamin E, respectively, on nicotine-hemoglobin (Hb) adduction in vivo. The results demonstrated that these dietary constituents induced remarkable decrease of nicotine-Hb adducts. The inhibitory fact may afford an important clue of the chemoprevention of the potential nicotine-induced carcinogenesis. ...

PDF] Accelerator mass spectrometry in geologic research | Semantic Scholar
The ability of accelerator mass spectrometry (AMS) to measure very small concentrations of the nuclides 10 Be, 14 C, 26 Al, 36 Cl, and 129 I has led to many innovative applications in geologic research. To take advantage of this opportunity in the geosciences, it is important to understand how AMS works, how these nuclides are produced, and how they can be applied to geologic problems. We first discuss the basics of AMS, explaining what gives the method its ability to count small numbers of these nuclides. We review how these nuclides are produced and transported in the atmosphere, hydrosphere, and lithosphere. We then explain the ways that AMS is being used to solve a wide range of problems in geologic research by discussing specific applications in areas such as geomorphology, tectonics, climatology, hydrology, and geochronology.

Accelerator Waste: A New Challenge for Radioanalytics | 11th International Conference on Environmental Remediation and...
The Paul Scherrer Institute (PSI) at Villigen (Switzerland) operates the most powerful accelerator facility in Europe. Due to the increasing quantities of accelerator waste with almost unknown radionuclide inventory, the development of new radio-analytical methods is an urgent task. Besides the characterization by γ-measurements and dose rate determinations, also the investigation of long-lived radionuclides, being probably essential for a final disposal, is required from Swiss authorities. Chemical separation is necessary for the determination of the majority of these isotopes. As a representive example for such studies, the analytics of a beam dump assembly is introduced. Samples were taken from the target E beam dump station from the 590 MeV proton accelerator facility. The content of several radionuclides with half-lives between 2 and 107 years was determined by γ-spectrometry and, after chemical separation, by Liquid Scintillation Counting (LSC) as well as Accelerator Mass Spectrometry ...
Attempts to use accelerator mass spectrometry to detect fractionally charged particles in Nature - CaltechAUTHORS
The search for fractionally charged particles (FCP) in Nature is ultimately motivated by the belief that the fundamental constituents of the atomic nucleus are quarks, which have charge in integral units of k of the electronic charge. The reported observation of fractional charge in niobium by a group at Stanford University in 1981 has motivated many new efforts to detect FCP in the past few years. The techniques of accelerator mass spectrometry (AMSh) ave been successfully applied to this problem at several laboratories. The method generally involves the use of electrostatic analysis systems to separate the FCP from integrally charged ions, since the mass of the FCP is not known a priori. A variety of materials have been searched in these experiments and the most sensitive limits are at concentration levels of less than 10^(-18) FCP per atom of host material. ...

N2 - The view that human populations may not have arrived in the Western Hemisphere before about 12,000 radiocarbon yr BP1,2 has been challenged by claims of much greater antiquity for a small number of archaeological sites and human skeleton samples. One such site is the Homo sapiens sapiens cairn burial excavated in 1971 from the Yuha desert, Imperial County, California3-5. Radiocarbon analysis of caliche coating one of the bones of the skeleton yielded a radiocarbon age of 21,500±1,000 yr BP4, while radiocarbon and uranium series analyses of caliche coating a cairn boulder yielded ages of 22,125±400 and 19,000±3,000 yr BP, respectively5. ...
National Taiwan University Hightlightshe140514 1
The linear particle accelerator occupying the NTU Heritage Hall of Physics is not just the museums most treasured exhibit, it could even be said to be the museums raison detre, for without it NTUs physics museum might not have come to be.. Our accelerators story begins in 1932, when the Cockcroft-Walton Linear Accelerator was built at the University of Cambridges Cavendish Laboratory and carried out the first bombardment of an atomic nucleus in history. Two years later, Japanese physicist Arakatsu Bunsaku, who had studied at Cavendish, began working here at NTUs predecessor, Taihoku Imperial University. Prof. Arakatsu, backed by his Japanese and Taiwanese students, brought our accelerator into being by constructing Asias first Cockcroft-Walton Linear Accelerator. That same year, Arakatsu employed the accelerator to conduct the first artificial nuclear disintegration in Asia here on this very campus.. In the aftermath of World War II, after the university had been reorganized as NTU, ...

Help regarding intuition on particle accelerators | Physics Forums - The Fusion of Science and Community
The way it works is reasonably simple. As Im sure you know, you can use a Van de Graaf to produce a large positive potential on the terminal. If you place the terminal in a pressure vessel, you can use something like Sulfur hexaflouride (SF6) as the insulator, and get very high positive potentials (25 MV was the record. Van de Graafs in operation today top out at about 15 MV). So, youve got a positive terminal. Then, you can introduce charged ions. Now, depending on the geometry of the accelerator, these may be positive or negative. If you place your source of ions in the terminal, then they need to be positive, and they will be repelled away from the terminal, giving you acceleration. Add a few magnets, and some focussing elements, and you have a rather nice accelerator ...

Technology Transfer
Since 2012, the LPSC accelerator group provides a dedicated room for the commissioning of intense electron linear accelerators designed by an industrial partner (PMB). These machines are developed to generate high doses of X rays (up to 30 Gy/min).. Therefore, the commissioning phase of these accelerators requires a large shielding, which is currently not available on the partners site.. The bunker of the SARA cyclotron (accelerator stopped in 1997) supplies shielded rooms, well adapted to operate these intense accelerators. The SARA bunker has been converted to allow the installation and operation of the electron machines. Since then, several accelerators have been installed in the bunker for the commissioning tests.. ...
Proton Synchrotron Booster - Wikipedia
The Proton Synchrotron Booster (PSB), a synchrotron, is the first and smallest circular proton accelerator in the accelerator chain at the CERN Large Hadron Collider injection complex. It contains four superimposed rings with a radius of 25 meters, which take protons with an energy of 6988801088243500000♠50 MeV from the linear accelerator LINAC 2 and accelerate them up to 6990224304708179999♠1.4 GeV, ready to be injected into the Proton Synchrotron. Before the PSB was built in 1972, LINAC 2 injected directly into the Proton Synchrotron, but the greater injection energy provided by the booster allows more protons to be injected and a higher luminosity at the end of the accelerator chain. As part of the High Luminosity Large Hadron Collider upgrade, the PSBs injection energy is being increased for the same reason. LINAC 2 is being replaced by LINAC 4, which will provide an energy of 6989256348237920000♠160 MeV into the PSB. Another way LINAC 4 will enable the PSB to hold more protons is by ...

Results of L3 BGO calorimeter calibration using an RFQ accelerator - CaltechAUTHORS
A novel calibration system based on a radio-frequency-quadrupole (RFQ) accelerator has been installed in the L3 experiment. Radiative capture of 1.85 MeV protons from the RFQ accelerator in a lithium target produces a high-intensity flux of 17.6 MeV photons which are used to calibrate 11,000 crystals of the L3 BGO calorimeter. In this paper, we present results of the first fully successful RFQ run, taken in November 1997. We achieved a calibration precision of 0.6% in the barrel and 0.7% in the endcaps of the L3 BGO calorimeter. The RFQ-97 calibration proved to be the best one of all calibration techniques used in the L3 experiment. ...

Identification of fraudulent-age whiskies using accelerator mass spectrometry (AMS) radiocarbon (14C) analyses - Enlighten:...
The last 10-15 years have witnessed a massively increased interest in collecting rare, single malt whiskies, with auction prices ranging from a few hundred pounds to many thousands. Consequently, these products have become a target for fraudsters who are selling what appear to be genuine old, rare whiskies that are actually relatively modern products. While the distilling industry can apply a number of modern analytical techniques to determine whether or not a whisky comes from the claimed distillery, it cannot determine the distillation year with any great accuracy. However, it has long been recognised that radiocarbon (14C) measurements can be used to estimate the production year of wines and spirits produced during the last 60 years or so, where the spirit was produced from a single years plant growth. This has relied on comparing the 14C measurements on the spirit with the northern hemisphere bomb calibration curve, produced from 14C measurements made on atmospheric CO2 and single year tree ...
Beryllium dating | Accelerator Mass Spectrometry Laboratory
Beryllium dating is used to estimate the time a rock has been exposed on the surface of the Earth, as well as erosion and sedimentation rates.. Beryllium-10 is another cosmogenic nuclide. Like carbon-14, most of it is formed in the earths upper atmosphere. After formation, beryllium-10 binds to atmospheric dust particles or dissolves in atmospheric water vapor. It is transported to earth surface in rain so consequently it has a much shorter atmospheric residence time than carbon-14. It accumulates on the earths surface and depending upon the sedimentation regime in the local environment, it can be used to date surface accumulation rates, surface erosion rates, or for dating layers within ice cores. Its half-life is 1.39 million years.. Vanishingly small amounts of beryllium-10, carbon-14 and aluminum-26 are also created at the earths surface. The creation occurs within minerals the upper meter of rocks exposed directly to the sky. If rocks are undisturbed for millennia, differences in the ...
Plasma Wakefield Acceleration
Particle accelerators so far have relied on electric fields generated by radio waves to accelerate electrons and other particles close to the speed of light. But radio-frequency machines have an upper limit of tens of MeV (millions of electronvolts) per meter of beamline. At higher energies, the RF electric fields can break down and could even generate enough heat to melt accelerator components. So the only way to get more power from an RF accelerator is to build a longer, more expensive beamline.. Experiments indicate that plasma wakefield machines could generate tens of billions of electron volts per meter-as much as 1000 times more acceleration potential per length of accelerator-allowing smaller accelerators of tremendous power. Such a system would use speeding electrons or a laser pulse to create a charge wake in a sea of ionized gas, or plasma. Like a surfer on a good wave, particles would ride this plasma wake to greater and greater speeds. But there are technical challenges to overcome ...
Cureus | Treatment Planning for Self-Shielded Radiosurgery
A five degree of freedom, robotic, radiosurgical system dedicated to the brain is currently under development. In the proposed design, the machine is entirely self-shielded. The main advantage of a self-shielded system is the simplification of the systems installation, which can reduce the cost of radiosurgery. In this way, more patients can benefit from this minimally invasive and highly effective type of procedure. For technical reasons, space inside the shielded region is limited, which leads to constraints on the design. Here, two axes of rotation move a 3-megavolt linear accelerator around the patients head at a source axis distance of 400 millimeters (mm), while the integrated patient table is characterized by two additional rotational, and one translational, degrees of freedom. Eight cone collimators of different diameters are available. The system can change the collimator automatically during treatment, using a collimator wheel. Since the linear accelerator can only move with two rotational
