ITER的主要低温用户是超导磁体和80K热屏蔽。驱动ITER低温系统设计的关键要求是由于电磁场和核加热循环变化导致的磁体中的固有脉冲热沉积，以及使用大流量氦循环泵对磁体进行强制流动冷却。本文重点介绍了ITER低温系统的主要特点，包括减轻氦制冷机脉冲热负荷和最大限度地减少氦循环泵热负荷的研究结果。
The main ITER cryogenic users are the superconducting magnets together with the 80K thermal shields. The key requirements that drive the design of the ITER cryogenic system are the intrinsically pulsed heat deposition in the magnets due to electromagnetic field and nuclear heating cyclic variations, and the usage of large flow capacity helium circulating pumps for forced-flow cooling of the magnets. This paper highlights the main features of the ITER cryogenic system, including the results of studies to mitigate pulsed heat loads on the helium refrigerator and minimize the heat load from helium circulating pumps.
