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. | ||

| 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. | ||
