In order to (i) keep read noise down (suppress the "snow") and (ii) prevent cosmic ray hits from permanently raising the read noise level by damaging the detector, the EIT CCD is usually operated at a temperature of about -67 C. This temperature is achieved by passive cooling: the CCD chip is thermally contacted to a titanium "cold …
WebWhen system bakeout temperatures need not exceed 150° C, Viton A has been commonly used. This article describes measurements made recently on a new ultrahigh vacuum material called polyimide 1. It withstands intermediate temperature bakeout up to 300° C and has a lower outgassing rate than Viton A.
