CCD-world: CCD's for the vacuum UV

[Clive Standley]

The following was posted to CCD-world:

I'm doing some experiments in the vacuum UV (below 193nm) and using CsTe and
CsI
PMTs. I noticed that NIST has some SI diodes that it calibrates from 254nm
to 5nm.
This got me wondering.....how do CCD's respond below 193nm? I found some
data
>From Jim Lesser at Steward that shows Hafnium dioxide coated CCD QEs of
about 30%
at 200nm. Does any one know if there is measureable QE at say 150 or 121 nm.
