Abstract
A cell and gas‐handling system of the supercritical material for x‐ray absorption measurement are designed. The cell was made of stainless steel with a pair of Be windows of 3 mm thickness. The x‐ray path can be controlled by changing the distance between two Be windows. Electric cartridge heaters are embedded in the cell to control the temperature. With this system we have studied the supercritical state of CF3Br, whose critical point is 67 °C and 39.1 atm. The results of x‐ray absorption fine structure measurements for Br K edge for gaseous, liquid, and supercritical states of this material are presented together with the performance of the gas‐handling system.Keywords
