  Modern precise radial velocity spectrometers are designed to infer the
existence of planets orbiting other stars by measuring few-nm shifts in the
positions of stellar spectral lines recorded at high spectral resolution on a
large-area digital detector. While the spectrometer may be highly stabilized in
terms of temperature, the detector itself may undergo changes in temperature
during readout that are an order of magnitude or more larger than the other
opto-mechanical components within the instrument. These variations in detector
temperature can translate directly into systematic measurement errors. We
explore a technique for reducing the amplitude of CCD temperature variations by
shuffling charge within a pixel in the parallel direction during integration.
We find that this "dither clocking" mode greatly reduces temperature variations
in the CCDs being tested for the NEID spectrometer. We investigate several
potential negative effects this clocking scheme could have on the underlying
spectral data.
