Scientific paper

A double density (15 microns per pixel) RCA CCD has been tested for astronomical imaging and spectroscopy at the Canada-France-Hawaii Telescope. This particular sensor has been treated with an anti-reflection coating to enhance performance in the ultra-violet (UV). The CCD is compared to the 30 micron RCA chip that has been in operation at CFHT for some time. In many applications instrumentation and seeing quality on Mauna Kea demand better sampling than 30 microns. The RCA double density chip was purchased and evaluated with these particular constraints in mind. Although the read noise is not as low as with some other three-phase CCD's, the unique backside treatment and permanent UV enhancement provided by RCA do give some advantages over some other sensors currently used.
