Title: Exoplanet Tracker Major Upgrade and Instrument Performance Measurements
Abstract: We propose to have two T&E runs in September and October 2008 to have a major upgrade of the KPNO ET instrument hardware, implement a new instrument control system and measure its on-sky performance. We will replace the entire interferometer system, the fiber feeding system and calibration system with new ones. We will replace the instrument control system with a cloned system for the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS). With these major upgrades, we expect to reach 1-2 m/s long-term Doppler precision. The early lab measurements show that two separated beams trace each other with a Doppler precision of ~0.7 m/s when the interferometer temperature was stabilized to within 0.01^\circC. This upgraded ET instrument will be used for following up many planet candidates to be identified from the MARVELS survey and for public access to high precision RV measurements.
