As surfaces are exposed to tritium, they will inevitably accumulate it, leading to the tritium memory effect. In order to reduce this effect, e.g. in analytic systems, decontamination methods are required. UV/ozone decontamination is known to be an efficient method, but its fundamental mechanism is not well known. In a dedicated UHV-compatible experiment, this method will be investigated systematically. This work focuses on the pressure dependent ozone production and depletion rates, as well as equilibrium concentration. All three properties showed a linear dependence on pressure, but showed a change in slope over time, converging to a stable level. During UV/ozone exposure, a steady increase in CO concentration was observed in early measurements. Both effects indicate a cleaning effect of the setup's inner surfaces.

监测氚兼容系统中的臭氧产生和消耗率

当表面暴露于氚时，它们将不可避免地积累氚，导致氚记忆效应。为了减少这种影响，例如在分析系统中，需要净化方法。众所周知，紫外线/臭氧净化是一种有效的方法，但其基本机制尚不清楚。在专门的特高压兼容实验中，将系统地研究该方法。这项工作的重点是压力依赖的臭氧产生和消耗率，以及平衡浓度。所有这三个属性都显示出对压力的线性依赖性，但显示出斜率随时间的变化，收敛到稳定水平。在紫外线/臭氧暴露期间，早期测量中观察到二氧化碳浓度稳定增加。这两种效果都表明装置内表面的清洁效果。
