Number: pap. n. 16

Author(s) : FU B., ZHANG Q., ZHU P., et al.

Summary

The helium cryogenic system supplies 4.5 K supercritical helium cooling for the superconducting magnets in the EAST superconducting tokamak. Four helium turbines at low temperature are used in the 2 kW helium refrigeration system and their performance and reliability are very important for the continuously experimental operation of EAST tokamak. Our need was to design, manufacture and test them. Some analysis,manufacture and design of the helium turbine structure, the helium turbine’s testing process and some testing results are given.The starting up process and some operational experiences of the turbines are also present in this paper.
