Abstract :
An addition to the University of Washington´s Nuclear Physics Research Center the Van de Graaff Nuclear Accelerator Building is now taking shape on a hillside adjoining the existing cyclotron group of buildings on the university´s campus. A new type of Van de Graaff accelerator, with three stages of acceleration, will be installed in the new building. The three-stage, positive-ion accelerator and auxiliary equipment will be used to provide a precisely controlled source of high-energy charged particles necessary for advanced research and study in nuclear physics.
