냉동기를 부착한 극저온 용기의 온도 특성 연구

The techniques of cooling down cryogen are the important technique to make superconductors superconducting state at very low temperature, 4 K. Therefore, the techniques to maintain stably and efficiently cryogenic state become essential techniques in the industrial appliance of the superconductors. This study includes a pre-experiment to manufacture the cryostat of the superconducting magnet, and examine the temperature characteristic of the cryostat, and the capacity of the cryocooler.
