SENSEI: First results, status, and plans

Date:  Thursday, May 9th, 2019

Time: 4:00pm

Location:100 Willamette Hall

Speaker: Javier Tiffenberg, Fermilab

Abstract: I’ll present the status and prospects of the Sub-Electron Noise Skipper Experimental Instrument (SENSEI) that uses a non-destructive readout technique to achieve stable readout for thick fully depleted silicon CCD in the far sub-electron regime (∼ 0.05 e- rms/pix). This is the first instrument to achieve discrete sub-electron counting that is stable over millions of pixels on a large-area detector. This low threshold allows for unprecedented sensitivity to the largely unexplored, but theoretically well-motivated, area of sub-GeV dark matter models. We’ll discuss the reach and prospects of the SENSEI experiment currently under construction, which will use 100 grams of Skipper CCDs.  I’ll also present recent results from an engineering surface run and the lessons learned from a small scale prototype currently operating in the MINOS cavern at Fermilab.

Host: Tien-Tien Yu

All attendees are invited to attend a colloquium reception in the Willamette Hall, Paul Olum atrium at 3:40pm.
