SUMMARY:Special INPA SEMINAR - Karthik Ramanathan (University of Chicago)
DESCRIPTION:Speaker: Karthik Ramanathan (University of Chicago)\n \n\nTitle: Dark Matter Taking Selfies: The DAMIC Experiment \n\nAbstract: The DAMIC (Dark Matter in CCDs) experiment uses silicon charge-coupled devices (CCDs)\, traditionally employed for imaging purposes\, to detect potential ionization signals from dark matter interactions. These approx. mm thick devices feature an impressively low leakage current (< 10-21 A/cm2) and a very low energy threshold (40 eVee)\, making them ideal low-mass dark matter detectors. In addition\, their unique spatial resolution provides for effective identification and mitigation of environmental backgrounds. In this talk\, I will highlight recent dark matter-electron scattering limits from the experiment at SNOLAB\, discuss the kg-size next generation DAMIC-M detector funded for operation\, and show results from “Skipper”instrumented CCDs – a novel readout technique that allows for counting of individual charges\, with a demonstrated resolution of 0.07 e-\, which ushers in a new era of sensitivity to low-energy interactions.
