| Outline of Final Research Achievements |
We constructed a new experimental system to investigate the processes of shock vaporization and subsequent chemical reactions in an open system using targets including water ice. A new experimental chamber with a cooling stage down to 170 K and with a quadruple mass spectrometer was newly made. The chamber was set to the downrange of the two-stage light-gas gun placed at Planetary Exploration Research Center of Chiba Institute of Technology. As the first step of research development, we conducted hypervelocity impact experiments with pure-water-ice targets. We confirmed that impact-generated water vapor can be detected with a high signal-to-noise ratio. The developed experimental procedure is expected to be applied directly to a more complex target material, that is a mixture of water-organics-silicate minerals, with a minor modification.
