Abstract

A simple cryostat has been made to observe the transition properties of high temperature superconductors. Since the cryostat utilizes the latent heat of liquid nitrogen under reduced pressure, temperatures ranging from room temperature to 61K can be obtained with larger cooling capacity than other cryostats using liquid helium or miniature cryocooler. In this note, the construction and the ability of the simple cryostat are described.
