DESCRIPTION:Speakers: Qing Lin (University of Science and Technology of Ch
 ina)\nDual phase time projection chamber using liquid xenon as target mate
 rial is one of most successful detectors for dark matter direct search\, a
 nd has improved the sensitivities of searching for weakly interacting mass
 ive particles by almost five orders of magnitudes in past several decades.
  However\, it still remains a great challenge for dual phase liquid xenon 
 time projection chamber to be used as the detector in next-generation dark
  matter search experiments (~50 tonne sensitive mass)\, in terms of reachi
 ng sufficiently high field strength for drifting electrons\, and sufficien
 tly low background rate. Here we propose a single phase liquid xenon time 
 projection chamber with detector geometry similar to a Geiger counter\, as
  a potential detector technique for future dark matter search\, which trad
 es off field uniformity for less isolated charge signals. In this talk\, I
  will talk about the concept of such Geiger-geometry single phase TPC (GG-
 TPC). I’ll show preliminary studies of field simulation and signal recon
 struction\, which show that such single phase time projection chamber is t
 echnically feasible and can have sufficiently good signal reconstruction p
 erformance for dark matter direct search.\n\nhttps://indico.physics.ucsd.e
