A small-pixel CCD project

John,

FYI . .. the only small pixel Sandbox device that comes close to what we have
developed is the 2k(V) x 1k (H), 9-micron backside illuminated CCD packaged in
a PCB. It uses four dual-stage amplifiers for 30 frame/sec operation. Slow-
scan noise is relatively high at 3.5 e- rms (Ts = 4 micro-sec) and a full well
of 70,000 e- (non MPP).  The CCD was built on Sandbox III. However, devices
need to be built on 10-micron , 50 ohm epi material in the future (MTF
problem). 

There are six other formats on Sandbox V (Spectra series) to be built... the
largest being 4k (H) x 1k (V) .. . however, these are all 12 micron pixels
(LEDIT designs).  A 4k (V) x 4k (H), 9 micron pixel is in the design phase
(Sandbox IX). 

Why do you need to butt 8-micron pixels? Even a 4k dimension is small enough
to come up with decent yield (famous last words).

What is your diving record now? Are you going to sneak in a dive with the
upcoming eclipse? Jeff says he is going after your record next month.

 Our interest in joining a collaboration on the 1Kx4Ks could be enormous
 or low depending on the details.  We are desperate to get good
 spectroscopic CCDs.  I am waiting to see how various current CCD
 devlopment projects pan out at EEV, SITe, and LBL (hi-rho).  I have
 been nursing the idea of trying to organize a consortium to make the
 ultimate spectroscopic CCD, if these don't come close enough to our
 performance requirements.
