Description
The LANSCE Accelerator Modernization Project (LAMP) plans to replace the two existing 750-keV Cockcroft Waltons by a single radio-frequency quadrupole (RFQ), and to install a new 100-MeV drift-tube linac (DTL). LAMP will simultaneously produce H+ and H- beams with different timing patterns to serve multiple experimental facilities. A low energy beam transport (LEBT) is designed to transport H+ and H- beams from the ion sources into the 201.25 MHz RFQ, where the beams are accelerated to 3 MeV. A medium energy beam transport (MEBT) is designed to transport the beam from the RFQ to the DTL. The DTL accelerates both beams to 100 MeV. The LEBT and MEBT designs include beam choppers and rf systems that imprint the multiple timing patterns required by experiments. Here we describe a concept of the LAMP front-end and present particle simulation results for multiple beams relevant to the facility.
