DEIMOS is a general purpose, faint object, multi-slit, double-beam spectrograph designed to operate at the right Nasmyth platform of the 10 meter Keck-II telescope located atop Mauna Kea in Hawaii. It utilizes slitmasks to allow the spectra from many objects (approx 80 per barrel!) to be imaged onto a mosaicked CCD array. Some of the key features are wide spectral coverage (up to 5000 Å per exposure), high spectral resolution (down to ~1 Å), high throughput, and long slit length on the sky (32'.6, sum of both barrels). DEIMOS operates in three modes: direct imaging, single-object spectroscopy, and multi-object, long-slit spectroscopy. DEIMOS will share the Nasmyth platform with the UCLA IR instrument NIRSPEC
The Principal Investigator on this project is Garth Illingworth, with Joe Miller and Sandra Faber as Co-Principal Investigators.
