High current, high reliability negative ion sources for next generation accelerators

Objective

New research areas in the near future will require High Power Proton Accelerators. Among all these projects (ESS, SPL at CERN), some will use negative hydrogen ions produced in a Negative Ion Source (NIS). The increase of the intensity is a great challenge for these machines and the challenge is also important for the ion sources. The ions extracted from the source are then accelerated in a LINAC (linear accelerator) and injected into compressor rings.

These machines will need long pulses of negative ions, with intensity and reliability not yet reached simultaneously. The objective of this network is therefore to assemble all the competence in the European Union to respond to this ion sources technical challenge. A by-product of the study is the optimisation of the existing NIS in research infrastructures in the European Union and a better understanding of the relevant physics. Moreover new techniques are now developed. We believe that, due to a better understanding of the source operation, further progress will be possible in Nuclear Fusion where NIS are of importance.
