[en] The objectives of this proposal are twofold. One objective is to design and test (using the OSU Van de Graaff accelerator) a moderator assembly for a thermal neutron source for the treatment of superficial tumors by Boron Neutron Capture Therapy (BNCT). We will identify the current of 2.5 MeV protons which is necessary to treat a patient in less than one hour. Our second objective is to design and thermally test a target for our thermal and epithermal source of neutrons for BNCT. Our work to date in fulfilling these project goals is described in this document. 11 refs., 4 figs., 1 tab
