Four-circle diffractometer with three-axis energy analysis
The 4-circle setup with the advanced 3He dilution cryostat
This cryostat, the only one of its kind in the world as of 2009, can reach 65 mK. Its operation mode is independent of gravityation, which makes it possible to follow the complex rotations of a 4-circle diffractometer. The technique used is similar to the one used on cryostats shipped on stratospherical high-altitude balloons and satellites.
