Adjustable DC Power Supply Based on a Computer Power Supply

In current reactor installations, the problem of wear of structural material under the effect of a neutron flux exists. At the National Research Centre Kurchatov Institute-ITEP, based on the TIPr (Heavy-Ion Prototype) accelerator, work is underway to study the radiation resistance of new materials using accelerated ion beams that simulate neutron exposure. 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 make it possible to simulate the effects of sample transmutation in the zone of damage by heavy ions. It is planned to use a system of quadrupole magnetic lenses powered by adjustable direct-current sources to focus a beam of hydrogen and helium ions.
