DEVELOPMENT OF INJECTOR FOR ITEP HEAVY ION SINCHROTRON BASED ON LASER PLASMA GENERATOR

A schematic diagram of heavy ion injector based on laser ion sources is described. Two different basic laser configurations used in ITEP synchrotron. First laser excels in simplicity and consists of CO2 free-running laser that is applied for carbon target plasma heating and ionization at laser power density q=3∙10 12 W/cm 2 to create high current C 4+ ion beam. Second master oscillatoramplifier laser configuration intends for production super high laser intensity at a target to provide considerable charge state in a plasma of heavy elements (Al, Fe, Ag etc). This laser configuration is founded on original physical principle * that simplifies the installation and ensures high reliability for long term operation. Laser characteristics for the different laser scheme and ion current for injector outlet beam of C 4+ and Ag +19 are shown in this paper. The latter was accelerated in synchrotron for energy up to 100 MeV/u. * K. N. Makarov et al. Quantum Electronics (Russian), 2001, 31 (1), pp. 23÷29
