Earlier we reported an ion current jump which was observed at a fixed negative biased disc
potential in the 6.4 GHz ECR ion source at VECC, Kolkata. In a recent experiment with neon …

The 6.4 GHz ECR ion source that was indigenously developed a few years ago has been
operating continuously for injecting oxygen and neon beams to the cyclotron since 1997 …

The performance of the biased disk in the 6.4 GHz electron cyclotron resonance ion source
at VECC, Kolkata was studied at a pressure of∼ 1× 10− 7 Torr⁠. We observed an abrupt …

The electron cyclotron resonance (ECR) ion source is special type hot plasma machine
where the high temperature electrons co-exist with multiply charge state ions and neutrals. A …

Abstract The 6.4 GHz Electron Cyclotron Resonance Ion Source has been put into
continuous operation for injecting remarkably stable oxygen and neon beams to the …

The beam current in ECR ion sources can be enhanced by inserting a biasing electrode
near the ECR region on the injection side. We have experimentally studied the variation of …

[en] The first indigenous Electron Cyclotron Resonance (ECR) Ion Source was developed in
VECC in 1991 for injecting heavy ions into VEC to facilitate heavy ion acceleration …

Vacuum plays a major rule in Electron Cyclotron Resonance Ion Source (ECRIS). ECRIS
plasma discharge takes place in vacuum of the order of 10 {sup-7} Torr. The low-pressure …
