SUPERCONDUCTING MAGNET FOR MEASUREMEMT APPARATUS FOR SUPERCONDUCTIVITY

摘要

PURPOSE: A superconductive magnet device for evaluating superconductivity is provided to precisely measure the superconductivity of a superconductor according to a temperature and a magnetic field by using a race track type superconductive magnet. CONSTITUTION: A superconductive magnet(100) is formed with a race track type including a linear part. An inner chamber(200) includes a two step cooling unit(20), a superconductive current lead(210), and the upper side of a one step cooling unit(10). An outer chamber includes the one step cooling unit and surrounds the inner chamber. A vertical cooling block is connected between bobbins of a double pancake coil comprising a sub superconductive magnet. A thermal anchor is combined with the lower side of a horizontal cooling block.
