摘要

提出了一种净化液氩中电负性杂质的新方法。电子捕获机制已经被利用，电子是由强伽马射线源产生的。获得了高纯度和稳定性，可与标准气相法获得的纯度和稳定性相媲美。所获得的电子寿命(约0.8 ms，对应于1 kV/cm下约1.5 m的电子衰减长度)允许在一个长期稳定的大腔室中工作。

Argon purification in liquid phase (electronic capture)

A novel purification method applied to electronegative impurities in liquid argon has been developed. The electronic capture mechanism has been exploited, the electrons being generated by a strong gamma-ray source. High purity level and stability, comparable to those obtained with standard gaseous phase procedures, have been obtained. The electron lifetime obtained ( approximately 0.8 ms. corresponding to an approximately 1.5 m electron attenuation length at 1 kV/cm) allows one to work with a large chamber with long-term stability.<>
