DEVELOPMENT OF FAST MAGNETIC BEAM RASTER SYSTEM FOR INR ISOTOPE PRODUCTION FACILITY

With the aim of increasing of the efficiency of isotope production by providing a possibility of using a higher intensity beam on the target of the isotope production facility the fast magnetic raster system has been developed. The system consists of two pairs of coils included in the resonant circuits for generating of mutually perpendicular alternating magnetic fields as well as of power supply and control systems. The proton beam with the energy up to 160 MeV is scanned circularly (elliptically) with the frequency of about 5 kHz thus providing a full scan within the 200 mu s beam pulse with the maximum deflection up to 4.5 mm. The control system is based on the use of National Instruments cRIO-9076 integrated controller.
