Installation of the Legnaro ECR ion source

The mechanical parts of the 1 4.4-GHz Legnaro ECR (electron cyclotron resonance) ion source 'Alice', including the 24 bar NdFeB Halbach hexapole, were built. A newly designed extractor was implemented, with a tapered focus electrode and a reentrant puller. The source is expected to inject a superconductive linac, which is being completed, via an RFQ (radio frequency quadrupole). >
