Training on ELISE plants in 2016 Experience of ELISE operation in 2016

The ion source test facility Extraction from a Large Ion Source Experiment (ELISE) has been built at Max Planck Institute for Plasma Physics (IPP) Garching (Germany) and has been operational since December 2012. ELISE is an important intermediate step in the R&D roadmap that the European domestic agency Fusion for Energy has defined for the International Thermonuclear Experimental Reactor (ITER) neutral beam injectors. This new test facility for a large radio frequency ion source builds up on the experience gained during many years of successful operation of smaller testbeds at IPP. The purpose of ELISE is to extract a negative ion beam, at ITER relevant parameters, using an ion source with the full width (1 m) and half the height of the ITER source. ELISE is designed to generate plasma for up to 1 h and extract a H- or D- beam at up to 60 kV. Available power supplies allow beam pulses of 10 s every 150-180 s. Although ELISE is designed to be as close as possible to the ITER source, technical solutions have been implemented that allow considerable experimental flexibility. This report describes the training activities carried out in November and December 2016 with personnel from Consorzio RFX Padova.
