Abstract

An upgrade program for the LANSCE facility at Los Alamos National Laboratory aims at generating and transporting a 40-mA H^- beam with 80 keV energy and minimal emittance increase over the value currently measured with a 16-mA beam. Within a collaboration between the two laboratories, LBNL has built a new ion source that allows the extraction of a 40-mA beam. However, there are strong indications that a new layout of the extraction system/LEBT is needed to efficiently deliver a low-emittance beam with this increased beam current. An additional requirement for the new system is its adaptability to a range of beam currents between 20 and 40 mA. The design of this new system, based on extensive simulations with the code IGUN, is described in this paper
