Advances in Electrostatic Accelerators

Advances in the design and performance of electrostatic accelerators since 1969 are reviewed with special emphasis on the "forefront" accelerators that are currently leading in voltage capability. A comparison of the acceleration tube design offered by the National Electrostatics Corporation and the High Voltage Engineering Corporation will also be made. Other methods of increasing heavy ion energy by means of dual foil stripping will be discussed as well as the performance of a newly developed sputter ion source for the production of negative heavy ions with reliability and flexibility that greatly exceeds all other present systems. Finally, new developments in terms of both booster systems and very high voltage electrostatic accelerators (25-60 MV) are discussed.
