Multi cell ECR source

The possibility to build a hydrogen negative ion source using an array of ECR cells, operating at 2.45GHz, implemented in a magnetic multipole has been demonstrated. The magnetic field of the ECR cells provided a sufficient magnetic filtering effect. Thus cold plasma, suitable for negative ion formation by dissociative attachment, was produced in the vicinity of the ECR cells. This concept can be used both for negative ion sources for accelerators, and for sources required by magnetic fusion.
