A near-ambient-temperature-control cell for use with synchrotron x-ray powder diffraction

摘要

A low-cost cell was designed and built for synchrotron x-ray powder diffraction studies of materials with low m.ps. The cell was operated between 253 and 323 K with a temp. stability of better than 0.1 K. The construction of the cell allows free rotation of the sample during a scan to maximize the no. of powder grains in the reflecting position. The cell was used to study a transition from an ordered to a rotator phase in hexadecane occurring at 278 K and the results from that study are reported. [on SciFinder(R)]
