We have recently demonstrated, for the first time, single-electron response with a 675 um-thick skipper CCD fabricated on high-resistivity silicon. This is the first techonolgical milestone of the DAMIC-M program.
The extremely low noise of the skipper CCD will allow us to reach unprecedently low energy thresholds with DAMIC-M for an increase in sensitivity by several orders of magnitude in the search for light dark matter particles.
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.
