Science definition and the instrument sensor package for Critical Dynamics in Microgravity (DYNAMX)

Critical Dynamics in Microgravity (DYNAMX) has been selected to be one of the first two fundamental physics experiments to deploy to the International Space Station (ISS) on board the Low Temperature Microgravity Physics Experiments Facility (LTMPEF) M1 mission in 2005. DYNAMX will make very precise heat flow measurements across a column of liquid /sup 4/He as the sample transitions from its superfluid to its normal fluid states while supporting a heat flux Q. These measurements will permit the study of dynamical effects on this phase transition to long-range quantum order for the first time.
