Modernization of ECR-source DECRIS-3
The heavy ion accelerator DC-60 is equipped with an ECR source DECRIS-3. The source of multiply chargedions is designed to produce a beam of ions of various elements with a degree of ionization ≥ 1. The obtained beam of multiplycharged ions, after selecting the required charge, can be injected into an accelerator to obtain a higher energy, or transported toa physical installation for experiments with a low energy beam.This article describes the main characteristics of the DECRIS-3 ECR source. In the course of operation at the DC-60 cyclotron,prerequisites appeared for improving the characteristics of the ECR source, and also during the operation, the characteristics ofthe magnetic ﬁeld of the source worsened, all this led to the realization of the need to modernize the ECR source. Improvingthe characteristics of the ECR source makes it possible to increase the spectrum of capabilities of the cyclotron, which opens upnew prospects for experimenters.A technical justiﬁcation and terms of reference for the modernization of the ECR source were made jointly with NuclearReaction Laboratory staﬀ of the Joint Institute for Nuclear Research and the authors of the research. Changes in the ECRsource are shown schematically, and the magnetic ﬁeld is calculated. Constructive changes in the source will make it possible toobtain more highly charged and high - intensity ion beams, which expands the capabilities of the DC-60 cyclotron.
