A high-speed, low-noise CMOS 16-channel charge-sensitivepreamplifier ASIC for APD-based PET detectors

Description: A high-speed, low-noise 16-channel amplifier IC has beenfabricated in the HP 0.5 mm CMOS process. It is a prototype for use witha PET detector which uses a 4x4 avalanche photodiode (APD) array having 3pF of capacitance and 75 nA of leakage current per pixel. Thepreamplifier must have a fast rise time (a few ns) in order to generatean accurate timing signal, low noise in order to accurately measure theenergy of the incident gamma radiation, and high density in order to readout 2-D arrays of smal… more

Advantages of improved timing accuracy in PET cameras using LSOscintillator

Description: PET scanners based on LSO have the potential forsignificantly better coincidence timing resolution than the 6 ns fwhmtypically achieved with BGO. This study analyzes the performanceenhancements made possible by improved timing as a function of thecoincidence time resolution. If 500 ps fwhm coincidence timing resolutioncan be achieved in a complete PET camera, the following four benefits canbe realized for whole-body FDG imaging: 1) The random event rate can bereduced by using a narrower coincid… more

Labr3:Ce scintillators for gamma ray spectroscopy

Description: In this paper, we report on a relatively new scintillator -LaBr3 for gamma ray spectroscopy. Crystals of this scintillator have beengrown using Bridgman process. This material when doped with cerium hashigh light output (~;60,000 photons/MeV) and fast principal decayconstant (less than 25 ns). Furthermore, it shows excellent energyresolution for gamma-ray detection. Energy resolution of 3.2 percent(FWHM) has been achieved for 662 keV photons (137Cs source) at roomtemperature.

Effects of clone, silvicultural, and miticide treatments on cottonwood leafcurl mite (Acari: Eriophyidae) damage in plantation Populus

Description: Aculops lobuliferus (Keifer) is a little known pest of plantation Populus spp., which is capable of causing substantial damage. This is the first documented occurrence of A. lobuliferus in South Carolina. Previous anecdotal data indicated clonal variation in Populus susceptibility to A. lobuliferus damage. A damage rating scale was created to monitor mite damage in 2000-2001 in a short-rotation woody crop plantation; damage descriptions and seasonal phenology also were recorded. Foliar damage a… more

COMBUSTION TURBINE (CT) HOT SECTION COATING LIFE MANAGEMENT

Description: The integrity of coatings used in hot section components of combustion turbine is crucial to the reliability of the buckets. This project was initiated in recognition of the need for predicting the life of coatings analytically, and non destructively; correspondingly, three principal tasks were established. Task 1, with the objective of analytically developing stress, strain and temperature distributions in the bucket and thereby predicting thermal fatigue (TMF) damage for various operating con… more

Beam Tools for Geant4 (User's Guide)

Description: Geant4 is a tool kit developed by a collaboration of physicists and computer professionals in the high energy physics field for simulation of the passage of particles through matter. The motivation for the development of the Beam Tools is to extend the Geant4 applications to accelerator physics. The Beam Tools are a set of C++ classes designed to facilitate the simulation of accelerator elements: r.f. cavities, magnets, absorbers, etc. These elements are constructed from Geant4 solid volumes li… more

Final Topical Report, ''Multi-Dimensional Analysis of the Forced Bubble Dynamics Associated with Bubble Fusion Phenomena''

Description: A new adaptive grid, 3-D FEM hydrodynamic shock (ie, HYDRO )code called PHASTA-2C has been developed and used to investigate bubble implosion phenomena leading to ultra-high temperatures and pressures. In particular, it was shown that nearly spherical bubble compressions occur during bubble implosions and the predicted conditions associated with a recent ORNL Bubble Fusion experiment [Taleyarkhan et al, Science, March, 2002] are consistent with the occurrence of D/D fusion.

Chemical Treatment of US Department of Energy High Level and Low Level Waste to Obtain a Pure Radiochemical Fraction for Determination of Californium Alpha-Decay Content

Description: We have developed a chemical separation technique that allows the radiochemical determination of the californium a-decay content in Department of Energy (DOE) high level wastes from the Hanford and Savannah River sites. The chemical separation technique uses a series of column extraction chromatography steps that use Eichrom Industries' lanthanide and actinide plus 3 oxidation state selective Ln-resin(R) and the transuranic selective plus 4 oxidation state TRU-resin(R) to obtain intermediate pr… more

A CMOS Active Pixel Sensor for Charged Particle Detection

Description: Active Pixel Sensor (APS) technology has shown promise for next-generation vertex detectors. This paper discusses the design and testing of two generations of APS chips. Both are arrays of 128 by 128 pixels, each 20 by 20 {micro}m. Each array is divided into sub-arrays in which different sensor structures (4 in the first version and 16 in the second) and/or readout circuits are employed. Measurements of several of these structures under Fe{sup 55} exposure are reported. The sensors have also be… more

Effect of electrode density on cycle performance and irreversible capacity loss for natural graphite anode in lithium ion batteries

Description: The effect of electrode thickness and density for unpressed and pressed natural graphite electrodes were studied using electrochemical characterization. Pressing the graphite electrode decreases the reversible capacity and the irreversible capacity loss during formation. As electrode density increased, the capacity retention at high rate increased until 0.9g/cm{sup 3}, and then decreased. The cycle performances of the pressed graphite electrodes were more stable than the unpressed one. Pressing… more

Tests with ceramic waste form materials made by pressureless consolidation.

Description: A multiphase waste form referred to as the ceramic waste form (CWF) will be used to immobilize radioactively contaminated salt wastes recovered after the electrometallurgical treatment of spent sodium-bonded nuclear fuel. The CWF is made by first occluding salt in zeolite and then encapsulating the zeolite in a borosilicate binder glass. A variety of surrogate CWF materials were made using pressureless consolidation (PC) methods for comparison with CWF consolidated using a hot isostatic press (… more
