Even Lighter Particle Dark Matter

Prof. Chavarria's review article "Even Lighter Particle Dark Matter" was accepted for publication in the proceedings for the 14th International Conference on Identification of Dark Matter.

The article summarizes the current world-wide effort to search for sub-GeV dark matter particles from their interactions with electrons. Please find the preprint on the arXiv.


Postdoctoral position open!

We seek a creative, conscientious, and highly motivated candidate to spearhead the activities in the construction and commissioning of DAMIC-M. In addition, the appointee will have the opportunity to participate in the data analysis of the prototype detectors, and the R&D program at the UW to develop next-generation skipper CCD detectors (Oscura) and CMOS/selenium detectors for neutrino physics (Selena).

Results from a 11 kg-day exposure of DAMIC at SNOLAB!

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.


Single electron response achieved!

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.


Wire bonder works!

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.
