Hardware

4.5 - OUTGASSING

Outgassing is the release of a gas trapped in a material. It is a problem encountered in high-vacuum applications.

Materials not normally considered absorbent can release enough molecules to contaminate the vacuum and cause

damage to optical sensors, window coatings, etc.

Even metals and glasses can release gases from cracks or impurities but sealants, lubricants and adhesives are the

most common cause. Left unchecked, cooling performance would steadily degrade and therefore lead to increased dark

current. Furthermore, resulting electrochemical reactions would eventually destroy the sensor.

4.6 - EXTERNAL I/O

To enable additional functionality, the 4 x SMB connectors and Fischer connector from the iXon3 have been replaced

with a 26 way high density D-type connector.
