摘要: Abstract A measurement system for high temperature XAFS was developed investigating the local structure of hygroscopic molten salts like rare earth halides. solid sample enclosed in upper tank a quartz cell having sandglass shape under reduced pressure to avoid oxygen and moisture. The carried out an electric furnace capable highest 1273 K. After melting, runs down through melt path with 0.1 mm (or 0.2 mm) thickness lower tank. measurable energy limited be above 10 keV due absorption cell. We confirmed that expensive is possible this system.
