The JINR FLNR Heavy Ion Cyclotron Complex | |
|
||
| The FLNR's key directions of research: synthesis and study of properties of superheavy elements; properties and structure of light exotic nuclei, reactions with exotic nuclei. radiation effects and physical groundwork of nanotechnology. The scientific program of the JINR FLNR is implemented at U-400, U-400M and IC-100 cyclotrons. Accelerated ions are from Li to Bi with energies of 1-55 MeV/n. The annual operation time is about 15000 hours. To improve the efficiency of experiments on the synthesis of new elements the DC-280 cyclotron has been developed with the following parameters: ion energy - 4-8 MeV/n, masses of accelerated ions - 10-238, beam intensity (up to A=50) - 10 pmkA. The cyclotron is in the stage of assembling. After DC-280 commissioning, the reconstruction of the U-400 and U-400M cyclotrons will be performed. Parameters of the accelerators and the time schedule of reconstruction will be presented. | ||

Testing of Electronic Components at FLNR JINR Accelerator Complex: Current Status and the 7-Year Roadmap | |
|
||
| To meet the growing requirements of the Russian Space Agency (Roscosmos) in the electronic components testing, the first dedicated beamline was created in 2011. At 2014 the full value facility, consisted of three different beamlines, was successfully commissioned and routinely used. Since then, plenty of efforts were spent for upgrade of beamlines and elaboration of new methods of high energy heavy ion beam parameters evaluation and control under the SEE testing. The current status of the facility, the last news of the ion beam control at high level of LTE and the 7-year roadmap will be presented. | ||

| WEPSB038 | Multigap and Polyharmonic Bunching Systems at FLNR Cyclotrons | 446 |
|
||
| Since 1997, different variants of bunching systems have been used at the axial injections of FLNR cyclotrons to increase ions capture into acceleration efficiency. Combination of two single gap Sine and Line bunchers are used at the axial injections of U400 and DC110 cyclotrons. Since 2015, a single gap double RF harmonic buncher has been installed into the upper part of the U400M injection in addition to the lower sine buncher, the experimental results will be presented. For the HV axial injection of the new DC280 cyclotron, two variants of polyharmonic bunchers will be used: a multigap buncher and a single gap one. | ||
