Summary:To evaluate the applicability of multipixel Geiger photodiodes in experiments searching for dark matter, such device from different manufacturers were studied in liquid and gaseous xenon. The detection efficiency for scintillation radiation at a wavelength of 175 nm was <1%. Measurements in gaseous xenon have shown the presence of a component in the visible or infrared region and the absence of this component in liquid xenon. It has been concluded that further studies in this field must be performed using wavelength-shifting materials and photodiodes featuring the highest quantum sensitivity in the region of emission of the reemitter.
