This chip was sent as a second engineering chip as we were experiencing problems getting the first engineering chip CCD20 going. The UCO/Lick Detector Development Lab tested a number of MIT/Lincoln Labs CCID20 2Kx4K CCDs as part of the detector development consortium established by Gerry Luppino at the University of Hawaii. CCD29 was part of phase 2 development. The results are as follows

From graph of rate versus time, then
Rate = mT + c = 3.085 T + 1124.011
Alpha = m/c*c = 2.442E-06.
