INSTALLATION FOR RESEARCH physical and magnetic properties of high-temperature superconductors

摘要

The invention relates to the field of studies of the physical processes occurring in the rotating magnetic field of high-temperature superconductors can be used to study the lift of gravitational fluctuations and behavioral features rotating and stationary high-temperature superconductors in a magnetic field. The utility model is aimed at improving the accuracy of measurement, increase in the number of measured parameters, this is achieved in that the apparatus for investigating the physical and magnetic properties of high-temperature superconductors has a housing 38, the motor holder 1, which is a hollow cylinder with machined holes for the wires. In the holder of the engine 1 is placed PDM type engine 2 for rotating the measured sample 21. This is done by the inner tube 3, fixed to the motor 2 rotor type pin 4. PDM inner tube 3 is arranged coaxially within the outer tube 5. It is desired alignment is provided by retainer tube 6. This tube system latch has the function of centering the inner tube 3 and accurate transmission (without beats) the torque on the sample holder 17 which is mounted on the inner tube 3 with a threaded of the connections, and is a disc with flanges centralizer for the sample 18. The test sample 21 is placed in the centralizer 18 and the sample holder 19 and fastened by means of screws 7 to the sample holder 17. Directly below the sample 22. The coil 21 is a coil frame 23 is attached on the press fit lower lid 24 having a rim to ensure accurate alignment of the coil bobbin 23. The bottom cover 24 has holes for additional cooling coil 22 a liquid cooling agent (nitrogen). The bottom cover 24 having a disc-shaped ledge configured to seat tube 31. The centering bearing on the tube carrier 31 is provided by a clamp 15. The tube 31 acts as a carrier for the bracket and the structural member is attached to the lid-centralizer 8 by means of screws 7. The bottom cover 24 symmetrically arranged two holes with screw threaded adjusting screw 30. The setup 30 in the upper parts of the center, there are two holes for the rods 28. They are rigidly fixed after adjustment of its position in the adjusting screw 30 by means of screws 7. and rods 28 provided with an opening at the small pulley shaft 27, which in turn is small pulley 26. Via the pulley 26 and the small pulley 11 is stretched Kevlar thread 20 on which is mounted the holder sensor 10 having a corner form. The sensor holder 10 are arranged perpendicular to each other, two sensor 33. The housing 32, which is a pipe, is attached by means of screws 7 to the bottom cover 24 and serves a protective function. Stepper motor 9 DSHI series brings the system sensors in the thread-movement at a predetermined pitch. The necessary tension of Kevlar 20 yarn is ensured by the load 29. The test sample 21 is lowered into the cryostat 25 filled with cooling agent. On the upper cover 34 with screws 7 are fixed balance lever 35, which serve to trim the shoulders sample 21. weights lever 35 right hanger 37, the left suspension 36 is attached to the load bowl 16 and the sample 21, and the resulting weight measured using electronic scales 14 . by varying the speed of the sample 21, it is removed from the dependence of the gravitational and buoyancy.; In addition to the rotary operation mode setup for investigating the physical and magnetic properties of high-temperature superconductors can be operated in a stationary (stationary operation) by measuring the magnitude of the lifting force and the magnetic field in the gap. 1 PF, ill.1.
