Ion Source DECRIS-3

The ECR ion source DECRIS-3 is the copy of the mVINIS ion source which was designed and built in Dubna for the TESLA Accelerator Installation (Belgrade, Yugoslavia) in 1997. The assembly of the source was completely finished in the end of 1998 and then it was installed at the FLNR ECR test bench. The source was successfully tested with some gases and metals by using the MIVOC technique. In nearest future the source will be capable of ECR plasma heating using two different frequencies simultaneously. We are also going to use the DECRIS-3 ion source to design 1+ -> n+ technique for the DRIBs (Dubna Radioactive Ion Beams) project

Production of Ions of Metals with an ECR Ion Source at FLNR (JINR) cyclotrons

Two ECR ion sources : DECRIS-14-2 and ECR4M are presently in permanent operation at the FLNR cyclotrons U400M and U400, correspondingly. During last two years the major effort were made in production of high current stable ion beams of solids with the relatively low melting point in the mass range from Li to Bi. Both the evaporator and MIVOC methods were used. Among the solids such an exotic beam as 48Ca was produced at the U400 cyclotron with high efficiency. The main results on production of solid ions will be reported

RECENT DEVELOPMENT IN ECR ION SOURCES AT FLNR JINR

Abstract In the Flerov Laboratory of Nuclear Reactions (JINR) the development of ion sources based on the plasma electrons heating at the frequency of electron cyclotron resonance (ECR) is stimulated by the necessity of the accelerator complex (U-400, U-400M and CI-100 cyclotrons) upgrading as well as by creation of the new high current cyclotrons for basic and applied research. Several ECR ion sources have been operated in the Flerov Laboratory of Nuclear Reactions (JINR) supplying various ion species for the U400 and U400M cyclotrons correspondingly for experiments on the synthesis of heavy and exotic nuclei, using ion beams of stable and radioactive isotopes, for solid state physics experiments and polymer membrane fabrication. In this paper the new development concerned with modernization of ECR4M ion source, development of the new superconducting source DECRIS-SC2 and creation of the DECRIS-5 ion source for the DC-110 cyclotron complex will be presented
