| Abstract | Refractive Index Gas Thermometry (RIGT) is a primary thermometry technique where the thermodynamic temperature of a working gas is determined via microwave resonance measurements of the refractive index of the gas. Conversion from refractive index to gas density to thermodynamic temperature is facilitated by the use of virial expansions. Mote Carlo calculations will be presented for a RIGT arrangement employing a quasi-spherical copper resonator and helium as the working gas. Particular focus will be given to the sensitivity of the determined thermodynamic temperature to variations in experimentally-relevant parameters such as the gas pressure, compressibility of the resonator, thermal stability of the apparatus, and chosen virial coefficient values. |
