Description

Recent work demonstrated gas gain in the negative ion gas SF$_6$ using GEMs and Thick GEMs. SF$_6$ is a favorable gas for directional dark matter detection with a TPC because it provides low diffusion (at the thermal limit), strong sensitivity to spin-dependent WIMP dark matter (through the high fluorine content), and full-volume fiducialization (thanks to multiple negative ion species). In this work, we present results from a prototype detector showing successful operation of a Micromegas with strip readout in SF$_6$ gas, and discuss the prospects for directional dark matter detectors using this readout technology.
