title = "A new generation multi-object Doppler instrument for the SDSS-III multi-object APO radial velocity exoplanet large-area survey",
abstract = "We report performance of a new generation multi-object Doppler instrument for the on-going Multi-object APO Radial-velocity Exoplanet Large-area Survey (MARVELS) of the Sloan Digital Sky Survey III (SDSS-III) program. This instrument is based on dispersed fixed-delay interferomtry design. It consists of a multi-object fiber-feed, a thermally compensated monolithic fixed-delay interferometer, a high throughput spectrograph and a 4kx4k CCD camera. The spectrograph resolving power is R=11,000 and the wavelength coverage is 500-570 nm. The instrument is capable of measuring 60 stars in a single exposure for high to moderate precision radial velocity (3-20 m/s) measurements depending on the star magnitudes (V=7.6-12). The instrument was commissioned at the SDSS telescope in September 2008 and used to collect science data starting in October 2008. Observations of reference stars show that the measured photon noise limiting errors are consistent with the prediction for most of the measurements.",
