Conclusions
Our tests have shown that the superconductive magnetic system of the T-7 unit is operative and that the main design and circuit features adopted on the basis of preliminary investigations are appropriate. In particular, it was shown that it is possible to use a hydraulic parallel joining of numerous sections without additional adjustment. The superconductive magnetic system could be efficiently cooled by liquid two-phase helium rather than by “supercritical” cold helium which was frequently discussed in the literature.
The authors sincerely thank the friendly collective of engineers, designers, technicians, and workers who enthusiastically applied their efforts to the building of the Tokamak-7 unit and the execution of the tests.
