The ITER neutral beam test facility: Designs of the general infrastructure, cryosystem and cooling plant

European Research Centers and Associations as ENEA, FZK, IPP, UKAEA and CEA are involved in the design of the first ITER neutral beam (NB) injector and the ITER neutral beam test facility. A total power of about 50MW will have to be removed in steady state on the neutral beam test facility (NBTF). The main purpose of this task is to make progress with the detailed design of the first ITER NB injector and to start the conceptual design of the ITER NBTF. The general infrastructure layout of a generic site for the NBTF includes the test facility itself equipped with a dedicated beamline vessel and integration studies of associated auxiliaries such as cooling plant, cryoplant and forepumping system.
