Abstract

The NEID Port Adapter is the interface between the WIYN 3.5m Telescope and the NEID fiber-fed spectrometer. The spectrometer requires the stellar jitter to be controlled for 90% of the time to within 50 milli-arc seconds for visual magnitudes 12, and 200 milli-arc seconds for V-magnitudes 12-16. The NEID Port Adapter will use an Andor EMCCD with 13 micron pixels, and a tip/tilt piezo stage from nPoint with a lowest resonant mode of 479 Hz. We expect to meet the requirement with a closed-loop rate of 27 Hz. We have data taken at the WIYN telescope consisting of stellar centroids captured at a rate of 108.75 Hz, which we rebin to test the response at lower sampling rates. We present the results of feeding these waveforms into the nPoint controller and measuring the actual response.
