Abstract

The Rockets for Extended-source X-ray Spectroscopy (tREXS) are a series of NASA funded suborbital rockets that will make large field-of-view observations of the diffuse soft X-ray emission from the Cygnus Loop and Vela supernova remnants. The tREXS focal plane camera is made up of an array of 11 Vega-CIS113 CMOS detectors, with a 12th as the zero-order detector. To optimize the performance of the camera, a test setup was developed where a single CMOS detector can be characterized to determine which settings have the highest impact on detector performance characteristics such as readout noise. This paper will discuss this test setup, the initial testing that has occurred using an engineering grade detector, and the initial results on how changing bias potentials and pixel timings impact the readout noise. Improvements that will be made to the final focal plane camera electronics based on the findings in the initial testing will also be discussed.
