Abstract :

We report on different experimental behaviours of granular dissipative matter excited by vibration as studied during the 43rd ESA campaign of Airbus A300-0g from CNES. The effect of g-jitter is quantified through the generation of a rattle effect. The French-European teamís electromagnetic set-up is used, with 20Hz cam recording and high speed camera for a short duration (1s) during each parabola.
