Dr. Elsa Ariesanti MS-NE 2001; PhD NE 2011; Dr. Elsa Ariesanti attained her Ph.D.
after working on a project with Prof. McGregor to develop a
method to produce prismatic HgI2 crystals using horizontal vapor growth.
In doing so, she discovered the true chemical nature governing prismatic
HgI2 growth and developed more reliable methods of producing these crystals
with high purity materials. The new process allows for the growth of
elongated parallelepiped crystals with near perfect dimensions for
Frisch collar detectors. Dr. Ariesanti fabricated Frisch collar HgI2
detectors from her material, achieving room-temperature energy resolution
of 1.7% FWHM at 662 keV. At graduation, Dr. Ariesanti had 10 published
papers in archival journals and conference
records, and also one patent pending. Dr. Ariesanti worked at
Radiation Monitoring Devices, Inc. in Watertown, MA, for seven years. She
now works at Fisk University with Prof. Arnold Burger. Advisor: Douglas S. McGregor
