Abstract
A cryocooler system and a superconducting magnet apparatus having the cryocooler system include a cryocooler having a cool stage that cools a heat shielding unit and a thermal inertia that thermally contacts the cool stage of the cryocooler and has a high heat capacity. The cryocooler system reduces a temperature-increasing rate in a current lead by using the thermal inertia member when the temperature in the current lead is increased due to heat generated when an electrical current applied to a superconducting coil is ramped-up or ramped-down.
