The use of charge-coupled devices (CCDs) on ground-based optical telescopes has increased markedly over the past few years, in part due to the successful development and distribution of a number of Texas Instruments thinned, three-phase 800 X 800 detectors. It is relatively straightforward to achieve low readout noise, good charge-transfer efficiency, and low dark current from these devices. It is also possible to dramatically improve the blue and UV quantum efficiency by treating the backside surface of the detector. A UV flooding technique derived from original work at JPL which boosts the response of our two TI CCDs to nearly reflection limited values in the blue and UV is discussed along with some theory concerning silicon surface charging. This technique produces a photometrically stable detector that is well suited for use with ground-based optical telescopes.
