Figure 1.

A 3D half section A–A of the full cell is shown on the right. A is the internally water-cooled temperature control jacket, B the removable top pressure-seal assembly, C the stainless steel SAXS cell body, D the carbide through-rods that secure assembly B against an upward force when the cell is pressurized, E the diamond seat assembly (Fig. 2), F the specimen in a removable plastic insert suspended from the sample support column (Fig. 3) and G the diamond X-ray window. A port to the reverse side of the cell (not shown) is plumbed to the high-pressure pump to pressurize fluid in the space between the diamond windows. The assembly shown is about 15 cm tall. X-rays are incident along the arrow to G.
