Title: Searching for the WIMP Wind with the DMTPC Directional Dark Matter Experiment
Abstract: Dark matter direct detection experiments search for nuclear recoils caused by interactions with a wind of weakly interacting massive particles (WIMPs). The rotation of Earth around its axis will create a large daily modulation in the direction of the WIMP wind that may provide an unambiguous signature of WIMP dark matter. To search for this daily modulation, the Dark Matter Time Projection Chamber (DMTPC) collaboration is developing low pressure gas detectors with the ability to identify the directions of low energy nuclear recoils using optical readout. This talk will discuss the commissioning and operation of a new prototype DMTPC detector, the 4-shooter, in a surface laboratory at MIT. Upon completion of surface commissioning, this detector will be installed in the DMTPC underground laboratory at the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico.
Stimulants available 15 minutes before the talk.
