Abstract

We report on the characterization of four HAWAII Hybrid Si CMOS detectors (HCD) developed for use as X-ray detectors as part of a joint program between Penn State University and Teledyne Imaging Sensors (TIS). Interpixel capacitive crosstalk (IPC) has been measured for standard H1RG detectors as well as a specially developed H2RG that uses a unique bonding structure. The H2RG shows significant reduction in IPC, as reported by Griffith et al. 2012. Energy resolution at 1.5 & 5.9 keV was measured as well as read noise for each detector. Dark current as a function of temperature is reported from 150 - 210 K and dark current figures of merit are estimated for each detector. We also discuss upcoming projects including testing of a new HCD called the Speedster-EXD. This prototype detector will have a low noise, high gain CTIA to reduce IPC and read noise as well as in-pixel CDS and event flagging. In the coming year PSU and TIS will begin work on a project to incorporate CTIA and CDS circuitry into the ROIC of a HAWAII HCD like detector to satisfy the small pixel and high rate needs of future X-ray observatories.
