Title: A Low Temperature Two-Axis Goniometer for Azimuth Dependent Studies

Abstract

A novel insert was developed for top-loading liquid helium cryostats that allows a combined {+-}90 deg. sample tilt with a full 360 deg. azimuthal rotation. This sample stick is operational down to 1.5 K and was primarily designed for X-ray scattering in reflecting geometry. The device not being intended for scanning but positioning purposes, motion precision, resolution and repeatability specifications were relaxed to 0.1 deg. and readily achieved. This setup was initially designed for a specific cryostat and implemented at beamline ID20 of the ESRF but it can be easily adapted to similar top loading cryostats including cryomagnets. Initial results on the low temperature phases of CeB6 are presented.
