Description

As part of the LANSCE Accelerator Modernization Project (LAMP), the two existing 750-keV Cockcroft Waltons are planned to be replaced by a single radio-frequency quadrupole (RFQ). The new LAMP front-end needs to deliver beams with similar timing patterns to what is currently delivered to the multiple target stations. To accomplish this, the 3-MeV Medium Energy Beam Transport (MEBT) is designed with two choppers that help produce beam timing patterns required by the experimental user facilities. The new RFQ will introduce satellite bunches around the single high-intensity bunch that is required by the users. These satellite bunches need to be removed in the MEBT. This contribution describes the design of LAMP MEBT with a beam chopping scheme and presents simulation results.
