Cosmic Rays and Substrate Removal • Cosmic ray events produce clouds of detected signal due to particle-induced flashes of infrared light in the CdZnTe substrate; removal of the substrate eliminates the effect 2.5um cutoff, substrate on 1.7um cutoff, substrate on 1.7um cutoff, substrate off Substrate Removal Positive Attributes 1. Higher QE in the near infrared 2. Visible light response 3. Eliminates cosmic ray fluorescence 4. Eliminates CTE mismatch with silicon ROIC Images courtesy of Roger Smith 27
