The Experimental Research of Cyclotron DC-280 Beam Parameters

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.
