Abstract
A temperature-variable sample rotating cryostat has been developed in order to measure the angular and temperature dependence of the upper critical field in several single crystal Chevrel phase superconductors. In the cryostat, the temperature of the sample can be varied from 2 to 15K within an accuracy of ±10mK. The sample can be rotated with an accuracy of ±1°. in an adiabatic vacuum can around a horizontal axis at the center of our superconducting magnets which are able to generate magnetic fields up to 16.5T
