Energy Doubler Refrigeration System
The design concept of a central liquefier supplying satellite stations as well as failure nudes will be discussed. Performance data will also be presented.
Design and Performance of KEKB Superconducting Cavities and its Cryogenic System
The installation of the superconducting rf acceleration cavities and deflection crab cavities to the KEKB have been proposed and the R&D studies have been carried out extensively at KEK. The satellite refrigeration scheme is considered for the cryogenic system for the superconducting crab cavities. The R&D studies of the satellite refrigeration system and the high performance transfer line for this system have been started at KEK.
Prediction of net pressure on pressure equalized cavities
Abstract A numerical model has been developed for prediction of net pressure on pressure equalized cavities. The results based on this model show good agreement with those obtained from mock-up tests. Parametric studies verify that reductions in cladding load are possible, with proper design of curtain walls.
