Abstract:
    This invention discloses a method for carrying out scaling of ray radiation by relative photons, which applies homemade BBO crystals to prepare a 702.2nm degenerate relative photon source of high brightness to be received by a being scaled photon digital detector and a trigger photon digital detector, utilizes a particular parameter amplification method to locate optical path accurately to realizes the quantitative evaluation to quanta efficiency of photomultipliers and assesses the measurement uncertainty of 1.65% (k=2).
