Radiation test results on TK 1024 CCDs

Results are presented from tests on TK 1024 CCDs with a multipinned phase (MPP) implant built into an experiental mask set. The average dark current as a function of temperature increased by a factor of about 3 for the 5 krads of gammas, which is a 10-fold increase for the extra 2 krads of protons. Histograms of the dark current show two types of dark current, an average level change, and dark current spikes.
