摘要
The changes in helium leak rates with pressure and temperature from helium-cooled magnet vessels into insulating vacuum were measured. The leak rates increased by three orders of magnitude when the vessels were cooled from ambient temperature to 4.5 K. The changes in leak rates were found to be smaller than those of a Viscous flow through a capillary tube. (C) 2001 Elsevier Science Ltd. All rights reserved.
