The development and investigation of superconducting magnetic systems for physical experiments

Superconducting solenoids designed for different physical experiments are described. The solenoids are made of multifilament niobium titanium wires and are connected in series. The magnetic induction achieved at 4.2 K is 9.5 T and with the use of an iron yoke with magnetic flux concentrators an additional 1.5-2 T could be added to the operating volume of about 50 cm3. Various modified cryostats which allow operation for several days without liquid helium refilling and which permits a wide range of physical experiments are described. (author)
