Adjustable Direct Current Supply Based on Computer Power Supply

Abstract

In modern reactor installations, there is a problem of structural material wear under the influence of neutron flux. At the National Research Centre “Kurchatov Institute”, based on the TIPr accelerator (Heavy-Ion Prototype), work is underway to study the radiation resistance of new materials using accelerated ion beams simulating neutron flux. As part of the improvement of experiments at the accelerator, it is planned to create a second channel for simultaneous irradiation of the sample with both heavy ions and hydrogen and helium ions, which will allow modeling the effects of transmutation of the sample in the area of damage by heavy ions. To focus a beam of hydrogen and helium ions, it is planned to use a system of quadrupole magnetic lenses powered by adjustable direct current sources.
