New facilities for nucleon charge exchange at the Los Alamos Meson Physics Facility

Abstract

A progress report is given on the upgraded facilities at the Los Alamos Meson Physics Facility to support (p, n) and (n, p) charge-exchange studies at intermediate energies. These include a beam-swinger system, a 600 m flight path and neutron polarimeter for (p, n) reactions, and a medium-resolution spectrometer with a focal-plane polarimeter for (n, p). A general overview of the physics program being planned is also presented.
