An attractive, accelerator-driven, high flux thermal neutron beam facility is currently under construction at the INFN Legnaro National Laboratory (LNL), in the framework of the SPES research program. The experimental treatment of extended skin melanoma tumor, with a combined Boron Neutron Capture plus Photodynamic therapy approach (BNCT+PDT), is being investigated. The intense beam delivered by the 5 MeV, 30 mA (150 kW) cw RFQ which is the SPES proton driver, will be employed. One of the main elements of the BNCT facility is the construction of a reliable neutron producing target, based on the 9Be (p,n)9 B reaction. Two, original, beryllium-based neutron converter concepts have been developed and constructed for that purpose. Both fullscale prototypes already passed a series of thermo mechanical electron beam tests at operative and critical power conditions. The additional radiation damage tests are in progress. The Accelerator-Based Beam Shaping Assembly (AB-BSA) modeling is currently underway. The BNCT neutron irradiation facility, which main features are here reported, based on the saddle-type beryllium neutron converter, has reached an advanced design status.
