Description

We present the detailed design and hardware implementation required to build a laser wire scanner for H- bunches at the Los Alamos Neutron Science Center (LANSCE) in the low energy beam transport (LEBT) section of the LANSCE beam line. The presented design is modular and supports a variety of input laser beam orientations, as well as differing laser beam diameters and powers. A custom-built laser interaction point, and drift chamber are added to the current beam line to photo-ionize the H- secondary electrons and collect the freed electrons in a custom-built, high-speed Faraday cup detector. Our chamber design is modular and constructed to minimally impact LANSCE production, while also allowing for in-run cycle reconfigurations. This setup will allow for the testing of a variety of laser system diagnostics configurations at the LANSCE facility. Future directions for direct separation and spatially resolved detection of the neutral hydrogen and charged anions will also be presented.
