High-resolution gamma-ray detection using phonon-mediated detectors
Abstract
We are presenting the results of our ongoing efforts to develop a new type of focal plane detector for the 10 to 100 keV band with an energy resolution of 0.1 %. The device will measure energy and position by using microwave kinetic inductance detectors (MKIDs) to sense athermal phonons created by photon absorption in a dielectric substrate. We have fabricated a proof-of-concept detector of size 2 cm × 2 cm × 1 mm on silicon, which has demonstrated a baseline energy resolution of = 0.38 keV and = 0.55 keV at 30 keV.

© 2012 SPIE. September 25, 2012. Our research was carried out primarily at the Jet Propulsion Laboratory (JPL) and the California Institute for Technology, under contract from NASA. JPL's Microdevices Laboratory fabricated the devices used in this work. We would like to acknowledge the generous support of the Gordon and Betty Moore Foundation. Our work benefited greatly from the expertise of, as well as software developed by, the CDMS/SuperCDMS collaboration for the development of phonon-mediated particle detectors. We would also like to thank NASA's Space Technology Research Fellowship program for its ongoing support.Attached Files
