Photosensitive Gaseous Detectors for Cryogenic Temperature Applications [PDF]

open access: yesNucl.Instrum.Meth.A573:302-305,2007, 2005
There are several proposals and projects today for building LXe Time Projection Chambers (TPCs) for dark matter search. An important element of these TPCs are the photomultipliers operating either inside LXe or in vapors above the liquid. We have recently demonstrated that photosensitive gaseous detectors (wire type and hole-type) can operate ...
