Outgassing of CCD components in the vacuum

Components with strong outgassing

White vacuum grease (Tyreno Fluid, Vacugrease F-V2)

A similar spectrum as for the dark vacuum grease was measured. However, here the emissions only appear at higher temperatures and this grease seems to produce less potential contamination.

Constant lines emerged primarily at 75° C:

Line [amu]	Fragment ions
31	CF⁺
47	(not identifiable)
69	CF₃⁺

Semistable lines were found at:

Line [amu]	Fragment ions
40	C₃H₄⁺
45	(alcohol)
