Ion sources and axial injection
U400M Systems ModernizationFebruary-September 2007
• new axial injection line;• deep modernization of “warm” ECR ion source
(DECRIS-2);• new U400M central region ion optics for “low”
(4÷15) MeV/n beam acceleration;• new target–catcher system for 6He production with
local radiation shielding;• second system for “low” energy beam extraction;• new RF control system;• partial modernization of water cooling system;• new main magnet coil power supply source;• second superconducting 18-GHz ECR ion source
DECRIS-SC2 (under testing).
