A National Nuclear Structure Facility for Britain

A large electrostatic tandem accelerator has been designed to provide a nuclear structure facility in Britain. The machine is intended to operate initially at a terminal potential of 20 MV, with subsequent upgrading to 30 MV. The design of the facility is described, including the choice of main parameters, the beam optics, column construction, charging system, instrumentation and buildings. An extensive development programme on high voltage problems is being carried out.
