Use of an ECR Ion Source in the Large Electrostatic Accelerator

Abstract

A terminal ion injector using an all permanent magnet type electron cyclotron resonance (ECR) ion source has been constructed in the high voltage terminal of the vertical and folded type 20UR Pelletron tandem accelerator at Japan Atomic Energy Agency at Tokai. The new in-terminal injector made it possible to accelerate highly charged heavy ions which have not been obtained from the tandem accelerator. Beam energy and beam intensity have been remarkably increased and the noble gas ion beams have become available.
