Minnesota 10-, 40-, and 68-Mev Proton Linear Accelerator

Abstract

A description is given of those features of the University of Minnesota proton linear accelerator which extend the design of the Berkeley linear accelerator. These features are: three separate resonant cavities in series which produce, respectively, beams of 10‐, 40‐, and 68‐Mev protons, as well as appreciable currents when desired at energies between 25 and 68 Mev; a 500‐kv ac injector; a 200‐Mc amplifier system with three isolated output stages producing 0.6, 2.2, and 3.2 Mw of pulsed power; automatic frequency control systems; phase detectors; phase shifters; magnets; shielding and accessory equipment. The characteristics of the output proton beams are described, and a brief statement is made of the experiments being performed.
