<PRE>
Some data on the McGill's direct detection CCD in use at IMM-CAT
CCD type:
Pixel Array: 576x384
Pixel Size: 22.0 microns square
Full well capacity:
Digitizer: 14 bit/1 Mhz khz and
Serial No:
Absorption Efficiency: Approximately 40% at 7.66 keV
Photon spread:
#(CHECK) Si Conversion ratio: 2.65 eV/photon pair;
#(CHECK) Distance from Be window to CCD chip .543 inches
#(CHECK) ADU Gain: approximately 223 electrons/ADU (slow) and 38.4 fast
#(CHECK) ( had been 330 adu/phot with shallow depletion chip)
Conversion Noise:
Base temperature of Pelletier -40C (With air cooling)
spec settings: set address to 3 (EEV_576x384_3ph) for ccd chip type
(Do this by going to the detectors menu in the spec config editor and
changing the entry under the CCD) |
