摘要
We report the results of the tests of 150 detectors consisting of a scintillator strip and a wavelength-shifting fiber, read out by a metal-resistor silicon avalanche photodiode operating in the Geiger mode (MRS APD). Using weak flashes of a Light Emitting Diode we clearly see individual photoelectrons in the amplitude spectra of all MRS APDs. Based on these spectra we determine the gain, the relative quantum efficiency and the cross-talk of the MRS APDs. Using cosmic rays we measure the light yield, the efficiency, the response uniformity and the time resolution of the strips. The first results of the radiation hardness study using a proton beam are presented. The strips are to be installed at the Belle detector as a prototype of the future muon system for the Super B-factory.
