Scientific paper

We present early results of a four-month monitoring campaign (Sept.-Dec. 2006) of radial velocity long-term stability for sixty fibers on a new generation fiber-fed multi-object Doppler instrument, called the W. M. Keck Exoplanet Tracker(Keck ET). This instrument with 60 object capability, has been commissioned at the Sloan Digital Sky Survey (SDSS) 2.5-m telescope at Apache Point Observatory. Since its commissioning, the instrument has been used for a trial planet survey in May and June 2006. After the August engineering run, the instrument performance (throughput, image quality and Doppler precision) has been substantially improved. The Keck ET along with several clones will be used to conduct an All Sky Extrasolar Planet Survey (ASEPS) in 2006-2020 (Ge et al 2006, SPIE, 6269, 75).
