N2 - Installed in the Hubble Space Telescope (HST) in May 2009, the Wide Field Camera 3 (WFC3) is performing extremely well on-orbit. Designed to complement the other instruments on-board the Hubble Space Telescope (HST) and enhance the overall science performance of the observatory, WFC3 is effectively two instruments in one. The UVIS channel, with its pair of e2v 4K×2K CCD chips provides coverage from 200 to 1000 nm while the IR channel, with a Teledyne HgCdTe focal plane array (FPA) on a Hawaii-1R multiplexer, covers the 800-1700 nm range. This report summarizes the performance of the WFC3 detectors, including primary characteristics such as quantum efficiency, read noise, dark current levels, and cosmetics, as well as hysteresis prevention and the impact of radiation damage in the CCDs. In addition, we discuss effects in the IR detector such as persistence, count rate non-linearity, 'snowballs', and 'negative' cosmic rays.
