Description
Summary:A conduction cooled 8 T superconducting magnetic system with variable temperature insert is developed and tested. The cryomagnetic system is based on a commercial two-stage pulse tube cryocooler with cooling power of 1W at 4.2 K. The compact superconducting magnet is manufactured from NbTi wire and impregnated with epoxy resin by "wet" technology. The clear diameter of variable temperature space is 20 mm. The system provides temperature range of 5.5-300 K. The variable temperature space is filled by low pressure helium gas. To eliminate the overheating of the magnet at high temperatures the heat switch is used in thermal coupling between variable temperature space and the 4K stage. The system design, manufacturing and test results are presented.
