Test of phi(sup 2) model predictions near the (sup 3)He liquid-gas critical point

NASA is supporting the development of an experiment called MISTE (Microgravity Scaling Theory Experiment) for future International Space Station mission. The main objective of this flight experiment is to perform in-situ PVT, heat capacity at constant volume, C(sub v) and chi(sub tau), measurements in the asymptotic region near the (sup 3)He liquid-gas critical point.

Progress in the development of the MISTE flight experiment

The MISTE flight experiment plans to measure the specific heat at constant volume, C(sub v), and isothermal susceptibility chi(sup tau), near the (sup 3)He liquid-gas critical point. A new method for precisely determining the critical temperature is being evaluated and will be presented.
