Test Facility and Experimental Studies of Monocrystal HTS Pellets

The paper describes a multipurpose facility and the results of experimental studies of magnetization, trapped flux mapping, flux creep and low amplitude external AC magnetic field effects for YBCO monocrystal pellets, as well as the technique and results of measuring the volt-ampere characteristics of YBCO thin-wall cylinder at 77, 73 and 66 K. The facility features with placing the pellets in separate demountable liquid nitrogen cryostats, and using the set of Hall probes for studies of the evolution of the trapped magnetic field.
