MHz pixel rate deep depletion CCD

[Tony Abbey]

Our group here at Leicester has been developing high resistivity CCDs with
EEV for many years. These are for direct detection of X-rays, and we have
been able to procure up to 8000 ohm-cm EPI, and also very high res bulk
silicon. The latest CCDs for the XMM EPIC Xray astronomy satellite with
600 X 600 frame transfer 40 micron pixels and open-electrode structure for
good low energy QE at 100eV and high res for good QE up to around 15keV
are being tested now. Expected depletion depths are around 50 microns. 
 
We are not using EEV's latest fast low noise o/p node configuration, 
since we run at 5 microsec/pixel, but I believe the above CCDs can have 
the o/p node reconfigured to use the new structure, giving under 5 
electrons at 1MHz.
