Description

Detecting Earth-mass exoplanets using the Doppler method places
stringent requirements on detector stability. NEID is a new Doppler
spectrometer in development for the WIYN 3.5-m telescope at Kitt Peak
National Observatory as part of the NN-Explore partnership. The wide
spectral grasp of NEID (380-930 nm) requires a monolithic CCD detector
with a large area, small pixels, and excellent quantum efficiency across
the NEID bandpass. NEID employs a single, deep depletion CCD290-99
device from e2v having 9Kx9K pixels with 10-micron pitch and Astro
Multi-2 AR coating. We describe the results of a detector
characterization effort ongoing at the University of Pennsylvania. We
present measurements of the thermal variation of the detector package
during operation and a promising clocking-based method for reducing the
amplitude of these thermal variations to the mK level.
