Rotating-crystal monochromatic analysis of CsC₂₄ ex. HOPG (highly oriented pyrolitic graphite) in the range 300-110 K has revealed the structural transitions of Cs atoms submitted to the periodic potential of graphite. The three-dimensional stacking of the graphitic host, and the commensurate and incommensurate modulated structures of Cs, were determined.

A furnace able to reach 1123 K with a low-temperature gradient has been developed. It is designed to work on a curved CPS 120 detector with a transmission geometry.
