Low-temperature goniometer for X-ray and neutron diffractometry |
摘要 |
An Euler's goniometer for low-temperature diffractometry is rotatable about two turning circles and is arranged within a chamber filled with a coolant. Each of the turning circles - that is the chi-circle and the phi-circle - is constituted by a worm wheel which is driven in a stepwise manner by a worm and a stepper motor driving the worm. For providing a compact construction, the stepper motors and the actuated worms are arranged within the chamber as well.
