Abstract

A simple continuous flow cryostat designed for Mossbauer investigations with liquid nitrogen in the temperature range 77-300 K is described. The cryostat is built with a perspex sample holder, glass tubes and metallic frames for mylar windows which facilitate transmission of gamma rays. A copper - constantan thermocouple is used as the temperature sensor. The cryostat can be used in investigations where either the absorber or the source is at rest and the detector-absorber - source axis is horizontal. The performance of the unit is tested on low-temperature studies of stainless steel. © 1983.
