## Description

- description: The operando hydrogen microscope is an original apparatus that has
    been developed to visualize the time-dependent permeation of hydrogen through
    a sample. This apparatus is developed based on an ultrahigh vacuum scanning electron
    microscope (UHV SEM). The system consists of a lens system to focus ions produced
    by electron-stimulated desorption (ESD), an ion detector optimized for ESD-signal
    detection, and a two-dimensional measurement program synchronized with the position
    information of the electron beam. The developed detectors and electrostatic lenses
    enable highly sensitive detection of the ions. In this paper, we show the details
    of the instrumentation of the operando hydrogen microscope. We have succeeded
    in recording hydrogen and deuterium flowing from the rear of metals to the surface
    as a series of time-lapse images, showing the time-dependent changes in the surface
    distribution of hydrogen and deuterium. Deuterium permeation through the metal
    sample was dynamically visualized at the surface by the two-dimensional mapping
    of the desorbed ions induced by scanning electron beam irradiation.
