  2. Our Mentor

  3. The Problem • If super conducting wires are stressed by forces generated by high field magnets, their ability to carry electric current might be decreased

  4. Index Photo

  5. The Procedure Sample Mounting Machine Our Samples

  6. The Procedure • Ground with sandpaper • Polished with diamond paste

  7. Final Polish

  8. Acid Etch • Set sample in Acid Etch • Reveals Crystals • Crystals are the part that control the strain

  9. Optical Microscope Observation

  10. The Results

  11. Picture of crack Crack in Stainless Steel Sample

  12. Picture of thinning

  13. Conclusion • Stainless Steel- Cracks • Copper- Thinning • Based on the electrical results, the thinning is worse than the cracks

  14. 3-D photos

  15. Thanks! • Joan Crow • Carlos Villa • Bob Goddard • The Parent Drivers • The Magnet Lab
