Abstract :
CQ will exploit the superfluid transition of pure liquid 4He, in a microgravity environment, in order to study a critical point phase transition under non-equilibrium conditions. It will be conducted in conjunction with the DYNAMX experiment (critical dynamics in microgravity) on board the ISS, using the same hardware and electronics, and on the same mission. We call the combined mission DX/CQ.
