 The ITER Vacuum Group and their colleagues from Barcelona discussing the ITER Pre-Production Cryopump. The ITER cryo-pumps will be required to function in a fast cyclic mode - continuously pumping and recirculating the exhaust of the burning plasma, including the helium produced as a result of fusion. With such a specific mission to perform, a pre-production cryo-pump will be manufactured to test its functionality before the construction of all ten begins. In order to prepare the corresponding design work, a major meeting was held recently at the ITER site in Cadarche with the responsible officers from the European Domestic Agency, F4E, and the manufacturing firm Forschungszentrum Karlsruhe (FZK). "The design is based on significant complex modelling," the leader of the Vacuum Section, Robert Pearce, explained. "But if it is proven to be good, the pre-production pump may even be used on ITER for the hydrogen start-up phase." << return to Newsline #71 |
