The emission wavelength lies between 275 nm and 450 nm and the light yield per neutron is reported to be 20000 photons/MeV neutron energy

(a) What largest work function of a material used for a photo cathode would be acceptable that still allows detection of an emission originating from the scintillator?

(b) What is the maximum kinetic energy of electrons emitted from the photo cathode, given the emission wavelength range of the scintillator?

(c) How much charge is being generated per single neutron, assuming a 3 MeV neutron and a photon-to-electron conversion efficiency (quantum efficiency) of 15%? Would this charge be detectable if you use an Electrometer2 that has a resolution limit of 10 fC?
