Wide‐ranging experiments at Los Alamos meson factory Available to Purchase

The Los Alamos Meson Physics Facility is now running routinely at 100 microamps average beam current, and according to director Louis Rosen is the largest, most diversified nuclear‐physics facility in the world. One of several existing meson factories, LAMPF runs at the highest energy, 800 MeV, and eventually is expected to reach a maximum beam intensity of 1000 microamps. Meanwhile, Rosen points out, LAMPF accelerates more protons/second above the pion‐production threshold than the sum of all the proton intensities of all the accelerators all over the world.
