摘要：

The SITELLE Imaging Fourier Transform Spectrometer system being developed by l'Universite 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.
