Boron Neutron Capture Therapy (BNCT) is facing a new era where diferent projects based on
accelerators instead of reactors are under development. The new facilities can be placed at hospitals
and will increase the number of clinical trials. The therapeutic efect of BNCT can be improved if a
optimized epithermal neutron spectrum is obtained, for which the beam shape assembly is a key
ingredient. In this paper we propose an optimal beam shaping assembly suited for an afordable
low energy accelerator. The beam obtained with the device proposed accomplishes all the IAEA
recommendations for proton energies between 2.0 and 2.1 MeV. In addition, there is an overall
improvement of the fgures of merit with respect to BNCT facilities and previous proposals of new
accelerator-based facilities.
