Description

SENSEI (Sub-Electron Noise Skipper Experimental Instrument) is a direct detection dark matter experiment with detectors operating at Fermilab and at the SNOLAB underground facility. The experiment consists of silicon Skipper-CCD sensors that make multiple non-destructive measurements of the charge contained in each pixel, reducing the readout noise to a level that allows for resolution of single electrons. This low energy threshold, along with low rates of events which may contain up to four electrons, results in competitive sensitivity for low-mass dark matter candidates which interact with electrons over a wide range of dark matter masses. This presentation will give an overview of the SENSEI experiment and the current status after the successful commissioning of the first batch of science-grade sensors at SNOLAB.
