Location:  NRC Building, Rm1310

Speaker:   Alex Wright (Princeton University)

Title:     The DarkSide Dark Matter Program

Abstract: DarkSide is a direct detection dark matter program based on two-phase argon time projection chambers using argon collected from underground sources. DarkSide-50, the first physics detector in the program, will be deployed within the Borexino Counting Test Facility water tank in the Gran Sasso Laboratory (LNGS), Italy.  The unique combination of low background underground argon and a highly efficient neutron veto based on boron-loaded liquid scintillator should allow DarkSide-50 to convincingly demonstrate a background expectation of a fraction of an event in a 0.1T-yr exposure.  This will not only give the experiment the ability to probe for WIMP interactions with cross sections as low as 10E-45cm2, but also allow it to demonstrate the ability of larger, tonne-scale, detectors to operate background free. In my talk I will describe the DarkSide approach to the dark matter search and present results from DarkSide-10, a 10kg prototype detector that is currently being operated at LNGS, and a recent measurement of the Ar-39 activity in underground argon.

Stimulants available 15 minutes before the talk. The speaker is a candidate for an IPP Research Scientist position.
