|発明の名称||CRYOSTAT, SAMPLE MOUNTING APPARATUS, AND TEMPERATURE CONTROL METHOD|
PROBLEM TO BE SOLVED: To provide a cryostat for measuring the temperature over a range, extending from ultralow temperature of approximately 20mK or higher to a room temperature or higher, operating continuously, being manufactured and maintained at low cost, avoiding quenching and being miniaturized, and to provide a sample-mounting apparatus for quick and easy mounting/replacing of sample, and a temperature control method.
SOLUTION: The sample-mounting apparatus 5 is mounted to externally and detachably a low-temperature stage 9 in a vacuum atmosphere, and makes the temperature of the sample 31 increased locally by using a heater provided to the sample-mounting apparatus 5. The cryostat and the temperature control method are provided with the sample-mounting apparatus 5, directly bringing a sample holder 30 into contact with the low-temperature stage 9 and thermally coupling them at a first temperature-controlled level, thermally coupling the sample holder 30 to the low-temperature stage 9 via an attachment/detachment section at a second temperature level, and thermally decoupling the attachment/detachment section from the low-temperature stage 9 and disconnecting the thermal coupling at a third second temperature level.
