Mercuric
iodide (HgI2) is a semiconducting material suitable for applications
in room-temperature spectroscopy, including applications in nuclear physics
research. Although digital signal
processing (DSP) methods would offer significant advantages over analog methods,
DSP has not yet been optimized for HgI2 detectors.
In this project, HgI2
pulse data will be used to develop signal processing algorithms with a computer
emulation of the digital processing system.
Phase I will collect and analyze HgI2 pulse data, develop and
evaluate digital signal processing algorithms, and select an analog digital
converter, DSP, and pre-amplifier. A preliminary design of the pre-amplifier and
digital processing system will be developed for use with HgI2
detectors.
Commercial
Applications And Other Benefits as
described by awardee: While the most immediate commercial applications should be
for improved HgI2 nuclear physics detectors, improved digital processors also should find applications in
the general field of spectroscopy for law enforcement, criminal investigations,
and the detection of drugs, explosives, and biological and chemical components.
