Dr. Elsa Ariesanti

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. Advisor: Douglas S. McGregor
