| Abstract: | Bremsstrahlung photons followed by photoneutrons are the major radiation
hazards in high energy electron accelerators. These neutrons in high energy
electron accelerator are produced by Bremsstrahlung photons through photo
nuclear reactions. Monte Carlo code FLUKA was used to generate the photoneutron
spectra for 20 MeV, 450 MeV and
2.5 GeV electron (electron energies in Indus facility) hitting 4 mm of tungsten
target. The total photoneutron yield was calculated from the generated spectrum
for different target thicknesses. The results have indicated the isotropic
Giant Dipole Resonance (GDR) neutrons dominating the spectra for the above
three incident electron energies. The peak energy of the neutron spectra lies
between 0.1-1 MeV for these electron energies. The average neutron energy was
calculated and found to be 0.82 MeV, 4.09 MeV and 11.6 MeV for 20 MeV, 450 MeV
and 2.5 GeV incident electron energy, respectively. The details of the
simulation and results are discussed in the paper. |
