N2 - Radiation testing of perspective materials by fast neutron flux is an important task for large physical facilities such as the Large Hadron Collider or the International Thermonuclear Experimental Reactor. Such a source of fast neutrons is the accelerator based neutron source VITA, proposed, developed and actively used at the Budker Institute of Nuclear Physics. In 2022, a long experiment on generation of fast neutrons was carried out. During the experiment, materials for the Large Hadron Collider, International Thermonuclear Experimental Reactor, Institute for Theoretical and Experimental Physics were irradiated. The maximum neutron flux density per sample unit reached 2.9×1014 cm-2. However, the existing VITA facility was not originally designed for the deuteron beam, because it was initially created for research in the field of boron neutron capture therapy. Therefore, the power limit of the conducted deuteron beam is 10 times lower than that of a proton beam. The creation of a separate compact VITAmin facility for the generation of a powerful fast neutron flux will provide radiation testing of promising materials, as well as research in the field of fast neutron therapy of malignant tumors. The power supply for the VITAmin is proposed to be a symmetric cascaded Cockcroft-Walton voltage multiplier circuit. The high-voltage power supply will be located in the column to which the high-voltage electrodes of the accelerator-tandem are supplied. This paper presents the model, circuit, theoretical calculations, simulations and initial test results of the power supply.
