  Novel powerful electrostatic vacuum-insulation tandem accelerator had been proposed* and created at BINP. A 2 MeV 3 mA dc proton beam is obtained. Neutrons are generated by 7Li(p,n)7Be reaction in the near threshold mode**. Epithermal neutron flux is formed for the development of Boron Neutron Capture Therapy (BNCT) of malignant tumors. In this report results on proton beam obtaining, neutron flux generation and in vitro investigation are presented and discussed. This accelerator based neutron source looks like a prototype of compact inexpensive epithermal neutron source for the spread of BNCT. Plans on BNCT realization are declared. Also the facility is used for the development of nuclear resonance absorption technique for nitrogen detection, and for the investigation of neutronless fusion. First, 9.17-MeV gamma rays are generated by 13C(p,gamma)14N reaction at 1.76 MeV protons***. Second, we are ready to measure alfa particles energy spectrum of p+11B reaction.
