Design, performance and construction of a 2 MW ion beam test facility for plasma facing components

A new facility for the testing of plasma facing components (PFC) under high heat fluxes is presently under construction at IPP Garching. The aim of this facility is to provide thermal testing capabilities for high heat loaded divertor components which have both active water cooling and large outer dimensions. The water-cooled test chamber is equipped with two ion sources for positive ion beam production. Initially, only one of the two individually controlled RF ion sources with 1.1 MW maximum beam power will be used for heat loading tests within an operating regime from 5 to 65 MW/m(2) at the target position. This paper presents the details of the technical characteristics and the systems for vacuum generation, cooling, power supply, control, target diagnostics and data acquisition.
