Matching by solenoids in space charge dominated LEBTs
betatron matching solenoid coupling terms space charge force rotationally asymmetric
2009/9/17
The betatron matching of a rotationally asymmetric beam in space chargedominated low-energy beam transports (LEBTs) where solenoids are used forthe transverse matching has been studied. For better un...
