We describe a new high-resolution neutron-imaging detector. A neutron scintillator is imaged onto a photon-counting 2D imaging detector, with most of the scintillation used for event discrimination in this patented detector. Detection time and location are recorded, so neutron energy (time-of-flight) is measured for accelerator-based sources. We are currently fabricating a 25cmx25cm detector with 512x512 pixels and 100 ns time resolution. Results are presented for scintillator characterization measurements and imaging characteristics measured at IPNS, where the detector will reside.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.

SatCon Technology Corporation has completed design, fabrication, and the first round of test of a 373 kW (500 hp), two-spool, intercooled gas turbine engine with integral induction type alternators. This turbine-alternator is the prime mover for a World Sports Car class hybrid electric vehicle under development by Chrysler Corporation. The complete hybrid electric vehicle propulsion system features the 373 kW (500 hp) turbine-alternator unit, a 373 kW (500 hp) 3.25 kW-h (4.36 hp-h) flywheel, a 559 kW (750 hp) traction motor, and the propulsion system control system. This paper presents and discusses the major attributes of the control system associated with the turbine-alternator unit. Also discussed is the role and operational requirements of the turbine-alternator unit as part of the complete hybrid electric vehicle propulsion system.Copyright © 1996 by ASME
