The Vacuum Insulated Tandem Accelerator (VITA) was developed in the Budker Institute of Nuclear Physics to produce epithermal neutrons for boron neutron capture therapy in the 7Li(p,n)7Be reaction. The parameters of the generated radiation allow us to carry out in vitro and in vivo investigations of BNCT. In present moment the modernization of the facility elements is carrying out to meet the parameters required for clinical usage. As the first step of the modernization the stripping target and electrode apertures were optimized. The experiments on fine beam injection were carried out as well as experiments on high current transportation. The output current in the range 1.5-2.5 mA with proton beam energy of 1 – 2 MeV was obtaned in the routine regimes of generation. In presented work the results of the experiments and possible way to rise the proton current higher then 3 mA level with energy 2 MeV are discussed.
