| TUPSB36 | High Intensity Calcium, Chromium and Titanium Ion Beams from the Permanent Magnet ECR Ion Source DECRIS-PM | 303 |
|
||
| The first experiment at the Super Heavy Elements Factory (SHE) was launched at the end of 2020. The result of the experiment with a calcium ion beam and an Americium target is more than 100 events of the synthesis of Moscovium. The last two years have shown good capabilities of the Factory. These results allow us to start preparing for the synthesis of SHE with atomic number >118. For this experiment, we have to use heavier ion beams, such as titanium and chromium. The article describes the method, technique, and last experimental results on the production of metal ion beams such as 48Ca, 48Ti, 52Cr, and 54Cr ion beams at the DC-280 cyclotron from the DECRIS-PM ion source. | ||

| TUPSB37 | Modernization of the ECR Ion Source DECRIS-2M. Results of the First Tests. | 307 |
|
||
| The article describes the design of the modernized ECR ion source DECRIS-2M. The upgrade consists in increasing the magnetic field to improve plasma confinement and improve the source parameters. The modernization also made it possible to increase the inner diameter of the plasma chamber and replace the coaxial microwave power input by a waveguide. Redesigned injection chamber significantly expands the possibilities of production ions of solids using different methods. The article also presents the first results of experiments production of Ar, Xe and Bi ion beams from a modernized ion source. The results demonstrate substantial increase of the ion beams intensity. | ||

Ion Energy Measurement System on the Sample Surface for the High Energy Beam-Line of U400M Accelerator | |
|
||
| A heavy ion energy measuring system on the surface of the device urder test (DUT) is presented. This system is designed to measure the energy of ions on the high-energy beam-line (15-60 MeV/n) of the U400-M accelerator during SEE testing. A feature of this beam-line is that the vacuum chamber is separated from the ion guide by a foil and irradiation can be carried out both in the air and in vacuum. The beam-line is equipped with a standard ion energy measurement system based on time-of-flight method, but the direct measurement of the ion energy on the DUT surface is not performed. To measure the ion energy on the DUT surface, a dedicated system was created. Also, this system is used to measure ion energy after degraders, which are used to change the energy loss of ions and are installed in front of the DUT. The system consists of silicon and CsI scintillation detectors. The silicon detector is designed to measure the energy of short-range Xe, Kr and Bi ions. A CsI scintillation detector is used to measure the energy of long-range Ar, Ne, and O ions. The system is calibrated with TOF detectors. | ||

| FRA01 | Peculiarities of Producing 48Ca, 48Ti, 52Cr Beams at the DC-280 Cyclotron | 93 |
|
||
| 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. | ||
