Paper Abstract

The Wide Field Camera 3 (WFC3), a scientific instrument being prepared for the next Hubble Space Telescope (HST) servicing mission, has two detectors providing wavelength sensitivity from 0.2 to 1.7 microns. In a departure from previous HST detector enclosure designs that required extensive bakeouts, the WFC3 enclosures are vented to space. Several contamination analyses were performed to assist in the design and validation of the vent tube, detector and enclosure bakeout requirements, and instrument operational constraints. The benefits derived from the vented enclosure configuration are discussed, and the analysis techniques and implementation are presented.
