Figure 1
(a) Schematic illustration of the experimental setup. The flight tubes between the components are not shown. (b) Photographs showing the sample environment. The CT stage is composed of one vertical and two horizontal stages, a rotational stage along the vertical axis, and two horizontal stages on the rotational stage. (c) Photograph of the slit system. One of the silicon guard slits is attached to the upstream end of the helium tube. The downstream silicon slit in this photograph is moved out from the beam. (d) Schematic illustration of the home-made moist air generator. The scale bars in (b) and (c) indicate 10 mm. |
