After optimization of the injection of negative hydrogen ions and modernization of the stripping target 1.6 mA 2 MeV proton beam was obtained. Improvements of the accelerator to suppress accompanying electron current were introduced, and after making changes to protection system of high voltage power supply a stable proton beam with a current of 4.5 mA was obtained. Analysis of the experimental results shows that the beam is accelerated without losses. Obtaining of proton beam with the current of more than 3 mA offers the prospects of using of accelerators for BNCT in cancer clinics.
