N2 - In the second version of the VITA-II accelerator neutron source, outer corrugated ceramic surface is using in the vacuum part of the feedthrough insulator to increase the reliability of the tandem and increase the electrical strength, and the height of individual insulators is increased. When the highvoltage power source is turned 180 degrees, the lower part of the feedthrough insulator is located inside the rectifier sections. This allowed the accelerating potential to be supplied through the lower gas part of the feedthrough insulator to the high-voltage electrodes of the vacuum part of the accelerator directly from its sections. Which made it possible to create a uniform voltage distribution in the accelerating gaps of the tandem and eliminate the voltage drop in the gaps when dark currents appear. The changes made allowed to reduce the height of the facility, which is essential for placing the facility in a medical clinic. The report describes the changes made and the results of the experiments.
