Abstract
This chapter introduces the superconducting coils and their experimental tests. Section 6.1 introduces the configuration and winding techniques of the coils. Sections 6.2 and 6.3 present the critical current and AC loss measurement results. The experimental set-up for the critical current measurement at 77 K includes a cryogenic container, a power supply, instrumentation and a measurement system. The experimental set-up for AC losses measurement at 77 K includes a cryogenic container, a power supply, an inductive voltage compensation circuit and a measurement system. The critical current and AC losses of the coils are measured at 77 K. An experiment rig using cryocooler which can cool down to 20 K is also introduced.
