High resistivity CCDs

Richard,

Thanks for your response about the deep depletion CCD.

I wish you luck in finding support for this work. 
Unfortunately, I think EEV would only be in a 
position to take funds (to make such devices), 
rather than to provide funds.


I guess you know that EEV have made n-channel Si 
CCDs before, with ~ 1500  ohm-cm.  These worked
well, primarily for x-ray work.  Most production
involves the normal lower resitivity material, so
it is hard to justify runnning alternate batches,
except for a specific contract.  However, occasionally
devices will get made in this way.  EEV have also 
made some p-channel CCDs (small 02-06 devices) 
that worked well. Larger ones could clearly be
made.  Really it just needs the funding- as does 
the LBL work!

If you ever wanted to explore further the possibility
of getting anything made here, then please get in 
touch.  May I leave you to tell your collaborators
at LBL about our capability?

I'll be interested to hear how you get on with the 
f/1.7 spectrograph tests. 

Good luck,

Regards,
Paul
