The following two announcements are long overdue:

Dr. Michelangelo Traina started as our new postdoc on DAMIC-M on January 3rd, 2023!

Michelangelo received his Ph.D. from Sorbonne University in Paris and has been a DAMIC(-M) collaborator for the past three years.

Welcome!

DAMIC's results on the search for low-mass weakly interacting massive particles (WIMPs) was posted yesterday on the arXiv! Link.

We probed with the same nuclear target, and with an order-of-magnitude improvement in energy threshold, the parameter space that corresponds to the WIMP-signal interpretation of the excess of nuclear-recoil events recorded by the CDMS silicon experiment in 2013.

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.
