  1. Performance Characterization Of Candidate High Field Superconductors Using Integrated Reinforcement John W. Taylor Jr. National High Magnetic Field Laboratory July 10, 2006

  2. Superconductivity • Ability To Conduct Electricity Without Resistance At Temperatures Near Absolute Zero And, In Some Cases At Higher Temperatures

  3. Superconducting Wires • Efficient And Reliable • High Performance • Very Expensive

  4. Principal Procedures • Drilled Holes In Guide With Drill Press • Cut Wire And Copper Pipe • Solder Together • Pull For Tension • Measure Twist Pitch • Place In Tubes

  5. Main Materials • 0.8 mm Diameter Copper Wire Tin Plated • 1.5mm Diameter Copper Wire Tin Plated • Copper Pipe • Clamps • Tubes • Guide • Drill

  6. Precision & Accuracy • Tension • Speed • Distance Of Guide • Pitch Angle

  7. If Not Then. . . • The Wire Would Collapse Into The Center • The Wind Would Have Some Mishaps

  8. Twist Pitch • Distance Of Turns By Number Of Wires • Alternating Current Loss

  9. AC Loss • Eddy Current • Hysteresis

  10. Twist Pitch For Wires 0.8mm Diameter Wire • 1 x 3 2.0cm • 3 x 3 4.0cm 1.5mm Diameter Wire • 1 x 3 2.0cm • 3 x 3 4.0cm • 3 x 4 4.0cm

  11. Tough Times • Spacing Of Wires • Not Enough Tension • 3 x 5 And 3 x 6 Center Tubes

  12. Tubing • Wires Are Brittle • No Longer Superconductors • Tubes For Reinforcement • Because Of High Temperatures

  13. Cut Wires And Tubes Flatten Tubes Wind Together Test Mass Flow Rate Through Tubes Next Steps

  14. Acknowledgements • Mentor – Mr. Nick Brown • Head Scientist – Mr. Tom Painter • Outreach Coordinator – Mr. Carlos Villa • RIMS Director – Mr. Errol Wilson
