Pulsed operation ot a k928 pmi the photocathode of a hamamatsu r928 pmt is spot-illuminated by rectangularupulses of light. each pulse has a ? uration ? 2 ? s and contains on average 10,000 monochromatic photons (400 nm). the repetition frequency is 2 khz. the pmt is operated under iypical oconditions. question 1: what is the amplitude of the resulting anode current pulses (in ma)?question 2: what is the average anode current (in ma)? answer question 3: the maximum rating for the average output current is 0.1 ma. what repetition frequency (in khz) would produce this maximum rating all else being the same?question 4: the maximum rating for the average output current is 0.1 ma. what number of photons per pulse would produce this maximum rating all else being the same?
