The GAs Extraction and Analyses system (GAEA) for immediate extraction and measurements of volatiles in the Hayabusa2 sample container

Abstract Hayabusa2 returned surface samples from the C-type near-Earth asteroid (162173) Ryugu to Woomera, South Australia, in December 2020. The are expected contain not only volatile components reflecting its primitive nature, but also solar wind due exposure space. Such volatiles may partly be released inside sealed sample container enclosing particle destruction or heating a contingency case. In order collect and analyze prior container-opening, we set up gas extraction analyses system (GAEA: GAs Extraction Analyses system). requires ultra-high vacuum conditions, small line volume minimize dead simple configuration as well having an interface connect container. includes bottles for passive collection of at room temperature active liquid nitrogen temperature. A quadrupole mass spectrometer is installed gases line, non-evaporative getter pump used when noble analyzed. rehearsal operation GAEA was made ISAS/JAXA transportation tests Japan. November 2020, it transported safely Quick Look Facility (QLF) Woomera. It QLF worked planned analysis Here report concept, design calibration results outline analytical protocols applied Graphical
