a An image of the bottom of the HY2 sampler container. A certain amount of sample grains are visible. b A photograph of the surface of Chamber A of the sample catcher. Fine powdery grains are observed clearly by the illumination with a green LED light, which is useful in recognizing fine dust on the surface of materials. c An image of the cover of chamber A of the sample catcher attached on the surface of the electrostatic chuck in CC3-2. The inner surface of the chamber A of the catcher is covered with very fine powdery samples as the reflection on the surface was vague. d An image of sample grains in the chamber A of the sample catcher. This is referred from Fig. 1 of Clark (2022). e An image of a few sample grains of mm-size, which are preserved in the quartz glass container under the vacuum condition in CC3-2 to date. f An image of the powdery samples (pointed by a white arrow) inside the rotation cylinder of the sample catcher situated at the stage 4 in CC3-3. This was shot when the handling jig was about to be attached
