C4.00001: ADAM: Destroy transuranics and generate power from spent nuclear fuel for green nuclear energy Peter McIntyre The ADAM collaboration is developing a method to use accelerator-driven subcritical fission in a molten salt core to destroy the transuranic elements in spent nuclear fuel and drive breed-and-burn fission of the uranium in spent nuclear fuel. The method can be used to generate electric power at the same rate the plant operates today for the next century, and at the same time destroy the hazardous long-lived components of that fuel. Advances in the design and first steps to implementation will be presented. [Preview Abstract] |

C4.00002: Computational Fluid Dynamics using Graphic Processing Units Ruma Dutta To Better understand the hydrodynamics flow behavior in turbulence, particle-fluid flow have to studied numerically in dispersed phase based on Navier Stokes equation. generally detail simulation based on number of grids have been becoming increasingly complex in CFD physics. In today's super computer scenario, computational approach have been shifted to Graphic processing units. we have approached our two phase simulation using GPU units and developed code using GPU units.

C4.00003: Mercury and Selenium concentrations in Fish Samples from the Donna Reservoir and Canal System (Texas) Mohammad Hannan, Kareem Wahid, George Garcia, Mikael Nilsson, George Miller Mercury and selenium in fish from the Donna reservoir and canal system were studied using instrumental neutron activation analysis at the UC Irvine TRIGA{\textregistered} reactor. The samples contain measurable quantities of Hg and Se, although the amount appears to be within the Department of Health Services Health Assessment Comparison values for trace metals. The samples were analyzed without post-treatment, reducing the risk of errors from losses in the analysis method. Suggestions for improvements using this type of analysis are provided.

C4.00004: Hardware Engineering Design for 3D Magnetic Field Mapping Erin Ferrell Creating the design and operation aspects for an apparatus that will create a three dimensional map of the magnetic field surrounding the apparatus. The apparatus will include a Nintendo Wii console remote coupled to a magnetometer, an infrared beacon will also be made to calibrate the Wii console remote. Using the pinhole camera method to transform the data being viewed by the Wii console remote from a two dimensional into a three dimensional perspective. The final prototype should be able to function with high resolution and an accuracy to track small electrical anomalies. [Preview Abstract] |

C4.00005: Strong-Focusing Cyclotron: High-Current Proton Accelerator for ADS Fission, Medical Isotope Production, and Proton Cancer Therapy Peter McIntyre The cyclotron is one of the oldest and simplest particle accelerators, but the beam current that can be accelerated is limited by the overlap of succeeding orbits and by the inability with weak focusing to control the betatron tunes during acceleration. The strong-focusing cyclotron remedies both problems by using superconducting 1/4-wave cavities to provide sufficient energy gain per turn to fully separate orbits and by locating alternating-gradient beam transport channels in the sector dipoles to provide strong-focusing control of betatron motion. It can accelerate ten times more beam current than any existing accelerator: \textgreater 10 mA CW up to $\sim$ 800 MeV kinetic energy. The SFC provides the performance needed for ADS fission to destroy the transuranics in spent nuclear fuel; to synthesize 99Mo and other isotopes for nuclear medicine, and to provide high-brightness beams for pencil-beam cancer therapy.

C4.00006: Compact MRI of the breast: new magnetostatics and new superconducting materials for affordable breast screening Peter McIntyre, Kyle Damborsky, Akhdiyor Sattarov MRI imaging of the breast has been shown to provide enhanced early detection of breast cancer, but whole-body is not affordable for screening. New magnetostatics and new superconducting materials make it possible to produce homogeneous magnetic field at both breasts using a compact magnet that is suitable for staging in a doctor's office or mobile van.

C4.00007: Gas Electron Multiplier Radiation Detector Prototype Response and Its Latest Long Term behavior Study by Kpix Ying Wun Yvonne Ng, Jaehoon Yu, Seongtae Park, Andy White, Amit Bashyal, Timothy Watson The Gas Electron Multiplier (GEM) technology is one of the next generation radiation detector technologies that utilized the ionization in gaseous medium to detect electrically charged particles from various radiations. University of Texas at Arlington's advanced detector group has begun its work on GEM technology since the early 2000s to develop a new high precision detector for future particle detections. During the course of the past few years, data has been taken continuously to characterize the 30cmx30cm prototype detector. Statistical method has been developed to study the device's long term behavior. The effect of atmospheric pressure to the detector amplification has been compensated by a correction algorithm. In this talk, I will present the latest result of the long term stability study of the prototype detector and its ramification to future use. The study would be of a particular interested to researchers working on the sparks studies of the GEM detector. [Preview Abstract] |
