Test of SensL SiPM coated with NOL-1 wavelength shifter in liquid xenon

Abstract

A SensL MicroFC-SMT-60035 6x6 mm${}^2$ silicon photo-multiplier coated with a NOL-1 wavelength shifter have been tested in the liquid xenon to detect the 175-nm scintillation light. For comparison, a Hamamatsu vacuum ultraviolet sensitive MPPC VUV3 3x3 mm${}^2$ was tested under the same conditions. The photodetection efficiency of $13.1\pm 2.5$% and $6.0\pm 1.0$%, correspondingly, is obtained.
