Description

The LANSCE Accelerator Modernization Project (LAMP) will replace the front-end of the existing LANSCE accelerator, from ion sources through the end of the 100-MeV drift-tube linac. LAMP, and the RFQ Test Stand (RFQTS), assume high space charge neutralization in the low energy beam transport (LEBT) as solenoids are not sufficient to focus the beams and prevent beam blow up. We present the results of various simulations to find optimum parameters for the beam, the solenoids, the partial compensation factor, as well as emittances for best matching into the RFQ. We compare these results to experiments on the RFQTS beamline with argon gas and present the results.
