Abstract

Experimental values for the viscosity of the radioactive hydrogen isotope tritium (T2) are currently unavailable in literature. The value of this material property over a wide temperature range is of interest for applications in the fields of fusion and neutrino physics, as well as to test ab initio calculations. As a radioactive gas, tritium requires a careful experiment design to ensure safe and environmental contamination–free measurements. In this contribution, we present a spinning rotor gauge–based tritium-compatible design of a gas viscosity measurement apparatus, or ViMA, capable of covering the temperature range from 80 to 300 K.

ViMA -用于测量77 - 300 K之间氚粘度的旋转转子计

放射性氢同位素氚(T2)粘度的实验值目前在文献中是不可用的。这种材料在很宽温度范围内的特性对核聚变和中微子物理领域的应用以及从头计算的测试具有重要意义。作为一种放射性气体，氚需要仔细的实验设计，以确保安全和环境无污染的测量。在这篇文章中，我们提出了一种基于旋转转子压力表的气体粘度测量仪的氚兼容设计，或ViMA，能够覆盖80到300 K的温度范围。
