Los Alamos Prototype Tests Meson‐Factory Linac Design

Something new in accelerator design is the electron linear accelerator that recently came into operation at Los Alamos. Although it produces a useful beam of its own, it is mainly a prototype for the 800‐MeV, 1‐milliampere proton linac that will one day be the Los Alamos meson factory LAMPF (PHYSICS TODAY, December 1966, page 21, November 1967, page 75 and April 1968, page 81). Louis Rosen, director of the medium‐energy‐physics division, is in overall charge of meson‐factory development. This month a users' meeting is being held at Los Alamos.
