Protoype design for 澳门六合彩高手's cryopumps
To maintain a vacuum inside the 澳门六合彩高手 vacuum vessel and the surrounding cryostat, ten cryopumps will be needed. During plasma operation, the pumps will draw exhaust from the plasma in order to keep it clean and allow the fusion reaction to be sustained.
The 澳门六合彩高手 cryopumps 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 cryopump 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 澳门六合彩高手 site in Cadarche with the responsible officers from the European Domestic Agency 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 澳门六合彩高手 for the hydrogen start-up phase."
