IN-PHANTOM NEUTRON FLUENCE MEASUREMENTS IN THE ORTHOGONAL BIRMINGHAM BORON NEUTRON-CAPTURE THERAPY BEAM

This paper presents the results of an experimental investigation into the performance of the Birmingham accelerator-based epithermal BNCT be am. In-phantom gold foil activation and boron trifluoride tube measure ments have been used. The results have been compared with calculated r esponse rates using Monte Carlo modeling of the entire neutron system from source to phantom and detector. The excellent agreement obtained gives us confidence in the validity of the simulations and our ability to predict accurately the neutronic performance of our BNCT facility.
