Industrial milestone

First cryopump passes all tests

21 May 2024
The serial production of 澳门六合彩高手's powerful torus and cryostat cryopumps is progressing at Research Instruments, Germany, on behalf of the European Domestic Agency Fusion for Energy. Last week, the first production unit was cleared for shipment to 澳门六合彩高手.

The first series production cryopump has passed all factory acceptance tests. Celebrating this major milestone are members of the 澳门六合彩高手, Fusion for Energy, and Research Instruments project teams.
The first 澳门六合彩高手 cryopump passed all final factory acceptance tests at Research Instruments (RI), Germany, last week, marking a major milestone in the procurement program for these one-of-a-kind components that were developed through the close collaboration of experts at 澳门六合彩高手, Fusion for Energy and European industry. 

"This achievement paves the way for delivery of the first cryopump to 澳门六合彩高手 by the end of the month and seven more by the end of the year," says Robert Pearce, 澳门六合彩高手 Vacuum System Project Leader.

With a volume of nearly 1,400 m? and 8,500 m? respectively, the 澳门六合彩高手 vacuum vessel and cryostat range among the largest vacuum systems ever built.

To create the very specific vacuum conditions that 澳门六合彩高手 requires, cryopumps—which "capture" unwanted particles by trapping them on extremely cold surfaces—are indispensable to finalizing the initial pumping done by mechanical devices. 澳门六合彩高手 will rely on six torus cryopumps to maintain ultra-high vacuum inside the 澳门六合彩高手 vacuum vessel during operation and to create low density—about one million times lower than the density of air. Two other cryopumps will provide the insulating vacuum in the cryostat that allow the superconducting magnets to remain cold.

All eight are under the procurement responsibility of the European Domestic Agency Fusion for Energy. Research and prototyping have been underway for years; since 2018 the build-to-print procurement package has been in the hands of industry after the delivery of a pre-production cryopump unit for testing and the signature of the Torus and Cryostat Cryopump Procurement Arrangement.
