Development of FLNR JINR Heavy Ions Accelerator Complex (DRIBs III) | |
|
||
| At present time four isochronous cyclotrons: U-400, U-400M, U-200 and IC-100 are in operation at the JINR FLNR. Total operation time is about 10000 hours per year. The U400M is a primary beam generator and U400 is as postaccelerator in RIB (DRIBs) experiments to produce and accelerate exotic nuclides such as 6He, 8He etc. One of the basic scientific programs which are carried out in FNLR - synthesis of new elements which demands intensive beams of heavy ions. Now U-400 is capable to provide long term experiments on Са 48 beams with intensity of 1 pmkA. In order to improve efficiency of the experiments for the next 7 years it is necessary to obtain the accelerated ion beams with the following parameters. Ion energy 4-8 MeV/n Masses 10-238 Beam intensity (up to A=50) 10 pmkA Beam emittance less 30 pi mm*mrad. These parameters have underlain the project of new cyclotron DC-280. | ||

| FRYOR01 | Recent Development in ECR Ion Sources at FLNR JINR | 203 |
|
||
| 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. Six 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 ion source DECRIS-SC2 and creation of the DECRIS-5 ion source for the DC-110 cyclotron complex will be presented. | ||
