Dr. Alireza Kargar|
MS-ME 2005, PhD NE 2009; Dr. Alireza Kargar recently attained his Ph.D. after working on a project with Prof. McGregor
to develop high-energy-resolution, room-temperature-operated CdZnTe detectors.
Dr. Kargar fabricated Frisch ring CdZnTe detectors with energy resolution below 0.9% FWHM at 662 keV and HgI2 Frisch ring
detectors 1.7% FWHM at 662 keV. Dr. Kargar's CdZnTe detectors
operated with no pulse height correction with a simple commercial off-the-shelf preamplifier. The detector volumes ranged
from 0.2 cubic cm up 3.5 cubic cm. At graduation, Dr. Kargar had 22 published papers in archival journals and conference
records. After graduation, Dr. Kargar worked at Radiation Monitoring Devices, Inc. in Watertown, MA for over 5 years.
Dr. Kargar now has the position of Radiation/Nuclear Scientist at Morpho Detection, LLC in Andover, MA.

Alireza Kargar grinds CdZnTe samples to remove saw damage, and to shape the pieces for lapping and polishing.
CdZnTe samples shaped to be lapped, polished, and etched. The samples will be fabricated into "non-contacting" Frisch grid gamma ray spectrometers.
Alireza Kargar demonstrates a gamma ray spectrometer for engineering open house.
