Abstract

We have demonstrated that hole-type gaseous detectors, GEMs and capillary plates, can operate up to 77 K. For 3 example, a single capillary plate can operate at gains of above 10 in the entire temperature interval between 300 until 77 K. The same capillary plate combined with CA photocathodes could operate perfectly well at gains (depending on gas mixtures) of 100-1000. Obtained results may open new fields of applications for capillary plates as detectors of UV light and charge particles at cryogenic temperatures: noble liquid TPCs, WIMP detectors or LXe scintillating calorimeters and cryogenic PETs.
