12. Project DRIBs (phase I): 6He ions were accelerated at the U400 cyclotron; The efficiency of the system was 1.5% (the projected value is 15%); a number of modernizations in the system units were made, which were aimed at increasing the efficiency of extracting 6He (8He) nuclei from the catcher and transforming them into the accelerated beam; a mechanical part of the system for extracting the 6He and 8He beams from U-400 was created; the systems of diagnostics of the extracted from U-400 6He and 8He beams, vacuum system for the beam lines and physical set-ups as well as control systems were developed. Intensive research and design works in the frames of the Project DRIBs (phase II): Modernization of the microtron’s system and transport line, design of the transport line delivering an electron beam to the uranium target; Design and testing of the target-ion source complex; Calculation and development of a transport line for beams of single-charged ions-products of uranium fission.

G.Shirkov, Basic Facilities, JINR Scientific Council, 05.06.2003 U400R cyclotron Project U400R based on the U400 cyclotron facility The main goals of reconstruction are: Increasing beam intensities for masses with A  50 and energy range near 5 MeV/nuclon up to 3 p  a. Variation of the ion energy on the target with coefficient near 5. The ion beam emittancies on the target on the level 10  mm  mrad. The ion beam energy spread on the target on the level (2  3)  10-3. Decreasing of the main magnet power consumption from 1000 kw up to 250 kw. Completion of the cyclotron system by modern equipment. Now near finishing is the phase of the computer simulation and starting the phase of the designing.
