First dark matter search results from a surface run of the 10-L DMTPC directional dark matter detector

The Dark Matter Time Projection Chamber (DMTPC) is a low pressure (75 Torr CF 4 ) 10 liter detector capable of measuring the vector direction of nuclear recoils with the goal of directional dark matter detection. In this Letter we present the first dark matter limit from DMTPC from a surface run at...

Description
Summary:The Dark Matter Time Projection Chamber (DMTPC) is a low pressure (75 Torr CF 4 ) 10 liter detector capable of measuring the vector direction of nuclear recoils with the goal of directional dark matter detection. In this Letter we present the first dark matter limit from DMTPC from a surface run at MIT. In an analysis window of 80-200 keV recoil energy, based on a 35.7 g-day exposure, we set a 90% C.L. upper limit on the spin-dependent WIMP-proton cross section of 2.0×10 -33 cm2 for 115 GeV/c 2 dark matter particle mass. Keywords: Dark matter; WIMP; Direction-sensitive; Time projection chamber
