Figure 1
(a) A schematic view of the furnace assembly. This does not show the upper hollow zirconia rod holding the thermocouple used for monitoring the temperature during experiments. The quartz glass tube channels the nitrogen gas injected into the bottom of the furnace and is used to prevent oxidation of the graphite susceptor at high temperatures. The X-ray beam passes through the target location to be imaged (i.e. sample in the graphite susceptor) without encountering the induction coils (in red). The curvilinear black arrows indicate the rotating part of the setup during X-ray tomographic experiments (induction coils are fixed). (b) The custom-designed (at Elettra) sample holder that allows continuous sample rotation while the gas delivery system is stationary. |
