Paper Abstract
The SITELLE Imaging Fourier Transform Spectrometer system being developed by l'Université Laval at ABB-Bomem
will require two identical CCD detector systems. Our requirements for the cryogenic system for these cameras are:
cooling to below 190 K, extremely low vibrational input from the cryogenic system (<1 mg RMS from 0-2 kHz), hands-off
operation over long periods of time and low original capital outlay and continued operation cost. These constraints
drove towards the selection of a Polycold PCC cooled system which exhibits relatively low vibrational noise and can
efficiently achieve the required cooling power in our target temperature range. This paper will present work performed
to passively mitigate high frequency vibrations imparted by the Polycold PCC cryo-head on the detector cryostat.
