Open with A Scintillator-PMT combo is used to measure the energy spectrum from a Na-22 source. (5 pts) Calculate the energy of the Compton edge highlighted in the spectrum. (10 pts) Calculate the pulse amplitude associated with the above Compton edge, given: • Scintillation efficiency = 12% • Wavelength of scintillation photon = 410 nm • Light collection efficiency = 60% . Photocathode quantum efficiency = 30% • PMT gain = 105,000 • Detector capacitance = 150 pF (5 pts) A Pb attenuator was added between the source and the detector. How would this affect the pulse amplitude of the full-energy peak? W Open with A Scintillator-PMT combo is used to measure the energy spectrum from a Na-22 source.
