In part (a) the furnace is shown mounted on the JEEP translation table along with the molten salt electrowinning cell. The X-ray beam (indicated by the green arrows) enters from the left through the slits marked (si). The analysis volume is selected by the slits just visible on the right at (sd). Part (b) shows the energy-dispersive detector system consisting of a semi-annular array of 23 liquid-nitrogen-cooled germanium energy-sensitive detectors 2 m from the sample position at an angle of 5° 2θ from the incident beam. The central detector (Ge-12) is labelled.
