Yesterday we completed the first DAMIC 4k x 2k CCD package at the University of Washington. The device is half the area of the CCDs currently taking data at SNOLAB but otherwise identical. This CCD is a candidate to go to Los Alamos over the summer for activation by a neturon beam. The goal is to perform an experimental estimate of the tritium that is activated in silicon by cosmic neutrons.
