Dr. Elsa Ariesanti|
MS-NE 2001; PhD NE 2011; Dr. Elsa Ariesanti recently 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 presently works at Radiation Monitoring Devices, Inc. in Watertown, MA.
