  1. First 2D cos-θ designs EuCARD2 WP10 Task 3 March 17th, 2014

  2. BSCCO Rutherford (cf. WP10.2 statusFeb 2nd, 2014) • Width = 9.5 mm • Averagethickness = 1.45 mm • t-edge = 1.391 mm / T-edge = 1.517 mm • 22 strands • Criticalcurrent= 6700 A -> • Je = 505 A/mm2 • Trans. pitch = 65 mm • + 100 µm insulation

  3. BSCCO 7blocks b9 • 5 T -> Je = 554 A/mm²

  4. BSCCO 6blocks b11 • 5 T -> Je = 550 A/mm2 B (T)

  5. BSCCO 5blocks b9 • 5 T -> Je = 553 A/mm²

  6. BSCCO Rutherford proposal • Width = 10 mm • Averagethickness = 1.45 mm • t-edge = 1.391 mm / T-edge = 1.517 mm • 24strands • Criticalcurrent= 7050 A -> • Je = 505 A/mm2 • Trans. pitch = ? (> 65 mm) • + 100 µm insulation

  7. BSCCO(10 mm)5blocks b7 • 5 T -> Je = 487 A/mm²

  8. BSCCO(10 mm)6blocks b9 • 5 T -> Je = 515 A/mm²

  9. YBCO Roebel(cf. WP10.2 statusFeb 2nd, 2014) • Width = 10 mm • Thickness = 0.88 mm • 15 tapes • Criticalcurrent= 3000 A • Je = 340 A/mm2 • + 100 µm insulation (toobig?) How to model RoebelcablewithRoxie?

  10. ‘Roebel’ 7blocks b11 • 5 T -> Je = 561 A/mm² (Joverall= 450 A/mm²) B (T)

  11. ‘Roebel’ 7blocks b9 • 5 T -> Je = 597 A/mm² (Joverall= 477 A/mm²)

  12. ‘Roebel’ 4blocks b7 • 5 T -> Je= 520 A/mm² (Joverall = 416 A/mm²)

  13. YBCO Roebel(cf. WP10.2 statusFeb 2nd, 2014) • Width = 10 mm • Thickness = 0.44 mm • 8 tapes • Criticalcurrent= 1700 A • Je = 386 A/mm2 • + 50 µm insulation (toosmall?)

  14. ‘Roebel’ 6blocks b9 • 5 T -> Je = 557 A/mm² (Joverall= 450 A/mm²) I likethis one!

  15. ‘Roebel’ 5blocks b7 • 5 T -> Je = 533 A/mm² (Joverall= 430 A/mm²)

  16. Questions • Mid-plane gap? • Flat on the mid-plane (alpha = 0)? • Maximum inclinaison of a cable? • Insulationthickness? • Inter-layer block alignment? • Inter-layer gap? • Symmetricalcopperwedges? • Number of blocks? • No iron: Je ~ 530 - 560 A/mm² • Iron pole + 0.25 T max (without Fresca2) -> -25 A/mm² Comments

  17. 100 mm 2x12 mm

  18. ‘Roebel’ 4x2blocks b5 • 5 T -> Je = 697 A/mm² (Joverall= 564 A/mm²)
