At the Stanford Linear Accelerator Center attention is shifting from construction and testing of the two‐mile machine to the actual experimental program. Large spectrometers, bubble chambers, spark chambers and special beams are being prepared for a variety of experiments that will utilize the unusually high resolution, intensity and energy of the accelerator.
WITH TRIAL RUNS NEARING completion, the Stanford Linear Accelerator Center is getting ready to carry out its initial experimental program. This program has been planned to expoit fully the special properties of the two‐mile‐long electron beam—its 20‐GeV energy, very good optical properties and great intensity. These features will permit the production of useful beams of electrons, positrons, photons, muons and even strongly interacting particles such as pions, kaons and antiprotons. The electron, positron and photon beams will have the highest energy presently available (except for very weak beams produced by the decay of neutral pions at the CERN and Brookhaven accelerators). The muon beam will be uniquely high in purity and can have up to 18.0‐GeV energy. For some experiments the pion, kaon and antiproton beams will be competitive with similar beams at the large proton accelerators, but in general they will not be superior.
