Abstract

An automatic temperature control mechanism was fabricated from readily available components and installed on an existing continuous flow helium-vapor cryostat as part of an atom-probe field-ion microscope. This control system eliminates tedious manual adjustment of the vapor flow rate. It is shown that the time needed to cool the cryostat from room temperature to a cryogenic temperature is reduced from 3 to 1 h. Within the 40-80 K range changes in the setpoint temperature are accommodated within 10 min. The temperature stability is better than 0.1 K.
