  1. Test Results for an Array-Based GM-APD Detector Before and After Irradiation Kimberly Kolb, Brandon Hanold, Joong Lee, Don Figer SDW 2013 Conference October 9, 2013

  2. The Detector • Photon Counting • Zero Read Noise • Geiger-mode avalanche photodiodes • 256 x 256 pixel array • Hybridized (silicon to silicon) • Developed with MIT Lincoln Laboratory with support from the Moore Foundation RIT / A. Sue Weisler

  3. Pre- and Post-Radiation Results Median DCR vstemperature results pre- and post-radiation Median DCR vs time over incremental radiation doses * this is an un-settled DCR value taken from in-situ measurements
