Toward Scintillator High‐Gain Avalanche Rushing Photoconductor Active Matrix Flat Panel Imager (<scp>SHARP</scp>‐<scp>AMFPI</scp>): Initial fabrication and characterization

Abstract

We demonstrate the feasibility of a solid-state HARP x-ray imager and have fabricated the largest active area HARP sensor to date. Procedures to reduce secondary quantum and dark noise are outlined. Future work will improve optical coupling and charge transport which will allow for frequency DQE and temporal metrics to be obtained.
