Abstract
We have characterized the e2v CIS113 16 μm pitch 4608 x 1920 back-illuminated CMOS (BICMOS) array with near Ultraviolet (NUV) sensitization surface processing and measured its quantum efficiency over the wavelength range from 150 to 350 nm.

The Cosmological Advanced Survey Telescope for Optical and UV Research (CASTOR), one of the top priorities in the Canadian astronomical community’s decadal plan, is a space-based survey mission that would provide panoramic, high-resolution imaging of 1/8th of the sky in the UV/optical (150-550 nm) spectral region. This small-satellite class mission would provide high angular resolution ultra-deep imaging in three broad filters to supplement data from planned international dark energy missions (Euclid, WFIRST) as well as from the Large Synoptic Survey Telescope (LSST). One of the leading technical risks on this mission is the UV sensitivity required to approach 26th magnitude in the near UV band.

In this paper we briefly describe the architecture of this new high speed, high sensitivity CMOS detector and report on the results of our characterization and the implications for the proposed CASTOR survey mission.
