| Popis: | Main features of Russian test facilities for experimental modelling of a cryosorption primary vacuum pump for the ITER are described. An ultra-high vacuum facility on the basis of helium cryosorption pump is used for study of vacuum and physical characteristics of the cryosorbent; the facility is designed for long-term operation with the tritium content up to 30 g. Tritium impact on physical and mechanical characteristics and service life of cryopanels are studied on the test facility, which includes a container for samples exposure to the tritium atmosphere. A large-scale high-vacuum facility on the basis of a cryosorption pump with circulating cooling has been built to study co-pumping and separate pumping of gas mixtures and regeneration modes. The following experimental facilities are under operation: supersonic cryocondensation facility and facility intended to deter-mine static and dynamie characteristics of helium isotopes pumping for various types of sorbents in the temperature range from... |
