The emission wavelength lies between 275 nm and 450 nm and thelight yield per neutron is reported to be 20000 photons/MeV neutronenergy
(a) What largest work function of a material used for a photocathode would be acceptable that still allows detection of anemission originating from the scintillator?
(b) What is the maximum kinetic energy of electrons emitted fromthe photo cathode, given the emission wavelength range of thescintillator?
(c) How much charge is being generated per single neutron,assuming a 3 MeV neutron and a photon-to-electron conversionefficiency (quantum efficiency) of 15%? Would this charge bedetectable if you use an Electrometer2 that has a resolution limitof 10 fC?
