DEVELOPMENT OF THE ECR ION SOURCE DECRIS-5M FOR THE CYCLOTRON COMPLEX DC-140

Abstract

The cyclotron complex DC-140, which is under development at the Laboratory of Nuclear Reactions, is designed to solve a wide range of applied research with the use of heavy ions accelerated beams. The research works on radiation physics, radiation resistance of materials and the production of track membranes are planned. Following the requirements of experiments DC-140 should accelerate the heavy ions up to fixed energies 2.1 and 4.8 MeV per unit mass in a wide mass range from Ne to Bi with the intensity up to 10¹² particles per second (for Xe ions). In accordance with the working diagram of DC-140 cyclotron the ion source should provide the ion beams with mass-to-charge ratio A/Z of the range from 5 to 8 (from Ne⁴⁺ to Bi³⁸⁺).
