“…The operating temperature of the interferometer is close to 10 mK, which makes it probably the coldest multiple-beam interferometer ever made. Path interferometry has the advantage of a low required light intensity [16] and allowing simultaneous observation of the global crystal shape and of the fine details of the solid/liquid interface. The vertical resolution in the interface position is a few mm, while the horizontal resolution of about 15 mm is limited by the pixel size of the slow-scan CCD camera sensor.…”

Faceting has been observed on 3He crystals investigated with a low-temperature Fabry-Pérot interferometer. Nine types of facets were clearly identified during growth of a bcc- 3He single crystal at a temperature of 0.55 mK, while previously only three types of facets have been seen. Because of the weak coupling between the liquid-solid interface and the solid lattice in 3He the facets are apparently too small to be observed in equilibrium. The number of facets observed in our experimental conditions is consistent with the theory of dynamic roughening.
