  3. 13. Are there any other superconducting busses not being monitored by a quench detection system: 13kA & 6kA & 600A
    Robert Henry Flora
    25/02/2009, 09:15
  4. 15. Mechanical details of the bypass diodes
    Knud Dahlerup-Petersen
    25/02/2009, 09:40
  5. 16. How were the diodes tested prior to installation
    Andrzej Siemko
    25/02/2009, 09:55
  6. 17. Stresses on diode joints
    Knud Dahlerup-Petersen
    25/02/2009, 10:10
  7. 20. Effects of standard component failures as well as radiation damage on the operation of the QPS (fail safe or not). What design features make the system fail safe? Details on the detection circuits.
    Reiner Denz
    25/02/2009, 10:50
  8. 19. What limits the maximum negative di/dt for the magnet systems
    Hugues Thiesen
    25/02/2009, 11:20
  9. 32. Which experiences have been gained from the accident with respect to the expected behaviour of the existing QPS. Did everything react as designed? Did quenches propagate along the magnet chain due to transients and sudden current changes?
    Sandrine Le Naour
    25/02/2009, 11:40
  10. 22. MI^2T limits for magnets, what are they and how where they developed. Time budgets for detection and energy extraction for the various magnet system.

  13. 33. Reserve
    25/02/2009, 14:30
  14. 34. Procedures used and the resulting traveler associated with the failed busbar joint. Ultrasound tests of joints.

    Fabio Formenti
    25/02/2009, 15:30
  18. 30. How does standard component failure effect the operation of the QPS? In particular, what will happen in case of a mains power loss? Does the system rely on the proper functioning of a UPS system? Is the redundancy system properly designed on all levels?
