Simulations of the LEDA LEBT H/sup +/ beam

The computer codes TRACE and SCHAR model the Low-Energy Demonstration Accelerator (LEDA) low-energy beam transport (LEBT) for 75-keV, 110-mA, dc H/sup +/ beams. Solenoid-lens location studies verify that the proposed LEBT design gives a near-optimum match to the LEDA RFQ. The desired RFQ transmission (/spl ges/90%) and output emittance (/spl les/0.22 /spl pi/ mm mrad, transverse) are obtained when PARMTEQM transports the file for the SCHAR-generated optimum beam through the RFQ.
