The next seminar in the joint UK seminar series will be given by Dr. Dan Faircloth (ISIS/RAL) on Ion Sources. The seminar will be given via Zoom at 16.15 UK time on Thursday 28th April and can be accessed on the seminar series Indico page.

A quick journey through ion sources, from the plasma pioneers and hot filament ion sources, to microwave ion sources and Electron Cyclotron Resonance (ECR) ion sources. Even higher charge states can be reached with Electron Beam ion sources. Vacuum arc and laser plasma ion sources are used for ‘hard to ionise’ materials. There are several good uses for negative ions, but how do you make them? Caesium is key to high current negative ion production, however the volume process can also reliably and cleanly create negative ions. The Low Energy Beams Group at ISIS is currently developing two world leading negative ion sources: the 150 mA 2X Scaled Penning Surface Plasma Source and an un-caesiated maintenance-free Inductively Coupled Plasma (ICP) negative volume source for ISIS operations.
