摘要：

A thermosiphon cooling system is being pursued as part of the superconducting undulator magnet development at Argonne National Laboratory. Analyses carried out at the University of Wisconsin-Madison address several unique features for the helium-filled cooling loop including sub-cooling associated with the hydrostatic head, the impact of a heat load deposited primarily along the horizontal channel, and two-phase flow characterization at extremely low quality conditions. Results of the analyses are compared with experimental measurements for a full-scale cooling loop. Both the analyses and measurements address the design objective of maintaining the superconducting windings well below their current sharing temperature by exploring the flow induced heat transfer to the single and two-phase regions of the helium cooling loop.
