摘　　要：加速器超导磁体失超会导致恒温器中液氦蒸发并泄放到隧道内,引发ODH(Oxygen Deficiency Hazard)风险。有效地利用数值模拟和风洞实验可以对泄放过程进行研究,并且给出安全泄放流态的判据。本文对国内外超导加速器安全泄放案例进行分析,总结出影响安全泄放的主要因素,为国内大型超导加速器安全泄放设计提供参考。The quench of superconducting magnets in accelerators can cause the evaporation of liquid helium in the cryostat and the potential releasing into the tunnel,resulting in the risk of ODH(Oxygen Deficiency Hazard).Numerical simulation methods and wind tunnel experiments can be efficiently applied to study the releasing process and providing the criteria for flow style of safety release.This paper researched and summarized the cases about safety release of superconducting accelerators globally,identified the main factors that may affect safety release,and provided references for the safety release design of large superconducting accelerators in China.
