Abstract
A neutron generator was investigated for a neutron source for BNCT. Neutron generators have some obvious advantages over nuclear reactors for this purpose. The neutron source is the reaction D(d,n)3He. Moderation is done with heavy water. The optimal thickness of the heavy water layer was found to be 18 cm. To reduce the number of source neutrons, the beam should be used at angular interval 400–500 to the forward neutron direction. A beryllium reflector of thickness 20 cm was found to increase the neutron fluence by a factor of 4. The beam is clean of gamma rays.
