Developing the DECRIS-5M ECR Ion Source for the DC-140 Cyclotron Complex

The DC-140 cyclotron complex now under construction at the Flerov Laboratory of Nuclear Reactions (FLNR) is designed for wide range of applied research using accelerated heavy ion beams, e.g., studying the radiation physics of solids, the development and production of track membranes (nuclear filters), and the radiation resistance of electronic components. To perform experiments, the accelerator must provide accelerated ion beams with two fixed energies: 2.1 MeV/nucleon and 4.8 MeV/nucleon in the mass range of Ne to Bi, with intensities of up to 1012 particles/s (for Xe ions) on the target. In accordance with the working diagram of DC-140 cyclotron, the ion source must provide ion beams with mass-to-charge ratios in the range A/Z = 5–8 (Ne4+–Bi38+).
