## Description

- description: Isotope imaging is commonly used to investigate the localization of
    trace elements and their isotopes. In situ noble gas analysis of meteorites revealed
    the distribution of primordial noble gases that were trapped in the building blocks
    of asteroids and planets during the early stage of the solar system evolution.
    Solar wind noble gases are among the primordial gases present in meteorites and
    were trapped through exposure to solar wind. Micrometer-resolution in situ noble
    gas analysis has not been achieved due to the lack of sensitivity and spatial
    resolution. The microscale imaging technique is crucial for identifying the carrier
    phase of the solar wind noble gases. We have developed 4He isotope imaging utilizing
    secondary neutral mass spectrometry with strong field postionization. This technique
    achieved a lateral resolution of 2 μm and a 4He detection limit of 2 ×1017 cm−3.
    This development allows for the study of a solar wind gas-rich meteorite, Northwest
    Africa 801 carbonaceous chondrite, with micrometer resolution. The solar wind
    4He carriers are fine-grained particles and are sparsely scattered in the matrix
    region.
