Popis: | An experimental setup was devised allowing high-accuracy radiation power measurements in the range of the order of 10−18–10−15 W. The use of a calibrated Fresnel prismatic attenuator in the design minimizes the error in determining the mean number of photos in each radiation pulse. Results are presented for measurements of the positive measure operator for a Hamamatsu H7422-40 photoelectric multiplier. |
