论文摘要
基于时间投影室的使用，开发了一种用于确定在CERN的Na62稀有KAON衰减实验中使用的液体K的纯度的系统。测量了511 keV伽马射线在液体krypton中吸收的电离电子的衰减，以估计纯度。该设置已通过从商业来源纯化的K纯化进行测试。
A system for determining the purity of liquid krypton employed in the NA62 rare kaon decay experiment at CERN was developed based on the use of a time projection chamber. The attenuation of drifting ionization electrons from absorption of 511 keV gamma rays in liquid krypton was measured to estimate the purity. The setup was tested with krypton purified from commercial sources.
