4. Cryogenic systems transition modes The original methods to compute the quasistatic and dynamic modes of the cryogenic system heat exchangers were proposed [4.1, 4.2]. The cryogenic systems transition mode research were fulfilled [4.3, 4.4, 4.5] both computation and experimentally.

Cryogenic systems for large superconducting units

5. The tokamaks cryogenic helium systems

The cryogenic helium system for the first superconducting Tokamak (T-7) was desinged, studied and tested [5.1, 5.2]. The magnet systems test bench cryogenic helium system was made and studied [5.1, 5.3]. As a result, 14 toroidal field coils of Tokamak-15 superconducting magnet were tested [5.1]. Then the unique cryogenic helium system for T-15 superconducting magnet was proposed and realized [5.1]. The cooldown and steady-state operation of this system together with T-15 magnet system were studied [5.1, 5.4]. At last, the ITER (International Thermonuclear Experimental Reactor) cryogenic system conceptual design was proposed using the test and working experience [5.5].

6. Accelerators cryogenic systems

The conceptual design of the large extended cryogenic systems was proposed [6.1], the analysis of UNK-3000 cryogenic system efficiency and reliability was fulfilled and optimum composition and disposition of cryogenic plants were proved [6.2].

7. The perspective tendencies of the cryogenic helium systems progress

The new high effective and high reliability cryogenic helium systems were proposed [7.1, 7.2, 7.3]. The original solution for compression helium in centrifugal compressors was proposed. The addition amont of R-13 (R-14) reuired into helium permits not only to increase the compression stage of a cryogenic unit efficiency and reliability and to use R-13 throttle-effect for cooling of helium gas in the preliminary stage of cryogenic plants [7.4]. The two-circuit cryogenic helium systems with sattelites were analysed and tested as efficiency and the most reliability cryogenic systems for large superconducting units [7.5, 7.6]. The ejector final stages of cryogenic helium plants were studied as instrument for fall of temperature and increase of helium circulation throooough cooled canals [7.6, 7.7].
