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 field of fusion, neutrino physics, as well as to test ab initio
calculations. As a radioactive gas, tritium requires 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 (ViMA) capable of covering the
temperature range from 80 K to 300 K.Comment: 11 pages, 3 figures, Tritium Conference 202
