|
||
| The main activities of Flerov Laboratory of Nuclear Reactions, following its name - are related to fundamental science, but, in parallel, plenty of efforts are paid for practical applications. In 2021, the main its directions are: the production of the heterogeneousμ- and nano-structured materials; testing of electronic components (avionics and space electronics) for radiation hardness; ion-implantation nanotechnology and radiation materials science. Basing on FLNR long term experience in these fields and aiming to improve the instrumentation, the Flerov laboratory of nuclear reactions starts the new project - the dedicated facility for applied science on the basis of the new heavy ion cyclotron DC-140. Following the user¿s requirements, DC140 will be the multi-particle, double - energy machine, capable with light and heavy ions up to bismuth (2.1 and 4.8 MeV/u). The "ion cocktail" mode will be one of the significant parameters of the new cyclotron. The last year’s efforts in the field of cyclotron practical applications in FLNR and general overview of the DC 140 project - the new FLNR facility for applied science, will be presented. | ||

|
||
| The main activities of Flerov Laboratory of Nuclear Reactions, following its name - are related to fundamental science, but in parallel a lot of efforts are paid for practical applications. Currently, work is underway to create an irradiation facility based on the DC140 cyclotron for applied research at FLNR. The beam transport system will have three experimental beam lines for testing of electronic components (avionics and space electronics) for radiation hardness, for ion-implantation nanotechnology and for radiation materials science. The DC140 cyclotron is intended to accelerate heavy ions with mass-to-charge ratio A/Z within interval from 5 to 8.25 up to two fixed energies 2.124 and 4.8 MeV per unit mass. The intensity of the accelerated ions will be about 1 pmcA for light ions (A<86) and about 0.1 pmcA for heavier ions (A>132). The extraction system based on four main elements - electrostatic deflector, focusing magnetic channel, Permanent Magnet Quadrupole lens and steering magnet. The results of numerical simulation of the electrostatic deflector of DC140 cyclotron are presented in this this paper. | ||

| MOPSA50 | Axial Injection System of DC140 Cyclotron of FLNR JINR | 209 |
|
||
| Flerov Laboratory of Nuclear Reaction of Joint Institute for Nuclear Research continues the works under creating of FLNR JINR Irradiation Facility based on the cyclotron DC140. The facility will have three experimental beam lines for SEE testing of microchips, for production of track membranes and for solving of applied physics problems. The injection into cyclotron will be realized from the external room temperature 18 GHz ECR ion source. The systems of DC140 cyclotron such as axial injection, main magnet, RF- and extraction systems and beam lines are the reconstruction of the DC72 cyclotron ones. The acceleration in DC140 cyclotron is carried out for two values of harmonic number h = 2,3 of heavy ions with mass-to-charge ratio A/Z within two intervals 5 - 5.5 and 7.5 - 8.25 up to two fixed energies 2.124 and 4.8 MeV per unit mass, correspondingly. The intensity of the accelerated ions will be about 1 pmcA for light ions (A<86) and about 0.1 pmcA for heavier ions (A>132). The design of the axial injection system of the DC140 cyclotron is presented in this report. | ||

| The first beam of 84Kr14+ ions was accelerated in the DC-280 on December 26, 2018 and extracted to the ion transport channel on January 17, 2019. In March 2019, beams of accelerated 84Kr+14 ions with intensity of 1.36 pmkA and 12C+2 ions with and intensity of 10 pmkA were extracted from the DC-280 to the beam transport channel with energy about 5.8 MeV/nucleon. In 2020-2021 years, beams of 48Ca7+,10+ ions with intensity up to 10,6 pmkA were accelerated and 7,1 pmkA were extracted from the DC-280 to the beam transport channel with energy about 4,51 - 5,29 MeV/nucleon. In 2021 year, beams of accelerated 52,54Cr10+ ions with intensity up to 2,5 pmkA were extracted from the DC-280 to the beam transport channel with energy about 5,05 MeV/nucleon and beams of 48Ti7+ with intensity up to 1pmkA and with energy about 4,94 MeV/nucleon The main task of the new accelerator is implementation of the long-term program of researches on the SHE Factory aimed on synthesis of new elements (Z>118) and detailed studying of nuclear- physical and chemical properties of earlier opened 112-118 ones. | ||

| FRA04 | The Experimental Research of Cyclotron DC-280 Beam Parameters | 102 |
|
||
| The DC-280 is the high intensity cyclotron for Super Heavy Elements Factory in FLNR JINR. It was designed for production of accelerated ions beam with intensity up 10 pµA to energy in range 4 - 8 MeV/n. The beam power is up 3,5 kW. The diagnostics elements shall be capable of withstanding this power. Moreover such intensity beam required continuous control for avoid of equipment damage. Special diagnostic equipment were designed, manufactured and commissioning. During the design the calculation of thermal loads was made. Some of them were tested before installation on cyclotron. Diagnostic elements used on DC-280 cyclotron are described in this paper. The special Faraday cup was designed for beam cur-rent measurement. The moving inner probe and multylamellar probe are inside the cyclotron. The Scanning two-dimension ionization profile monitor was produced for space distribution analysis of accelerated high intensity beam. Inner Pickup electrode system with special elec-tronic was created for beam phase moving analysis. Time of flight system based on two pick-up electrodes for energy measured was placed in transport channel. These and over diagnostic system were commissioned and tested. The results present in report. | ||
