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

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].
