cryogenic CCD operation

[Tim Hardy]

I have heard that CCDs cannot be operated at extremely cold 
temperatures (I'm looking at an application which would operate
around 30K). Does anyone have any information on this?
What is the failure mechanism? Has anyone tried it? What is the 
cutoff temperature?  Is there any published research on this topic?


Thanks for your help,

Tim
