Sliding electrical contacts for the Plasma Grid of the MITICA accelerator

The ITER Neutral Beam Test Facility (PRIMA) is plan ned to be built at Consorzio RFX (Padova, Italy). PRIMA includes two experimental devices: an ITER- s ize ion source with low voltage extraction called SPIDER and the prototype of the ITER Heating Neutra l Beam Injector (HNB) called MITICA. The purpose of MITICA is to demonstrate that all th e operational parameters of the ITER HNB accelerato r can be experimentally achieved with reasonable marg in, thus establishing a large step forward in the performances of neutral beam injectors in compariso n with the present experimental devices. This note describes the activities on the Multilam connectors for the MITICA Plasma Grid.
