AbstractThe experimental techniques for the measurement of diffusion coefficients have been developed in JAXA toward the utilization of microgravity on ISS. Recently, these techniques are applied to the measurement of diffusion coefficient in the normal gravity on the ground and are improved for the microgravity experiment in future. In this proceeding, the current status of the shear cell techniques and the experimental cartridge for microgravity experiments are reported.
