Presentation Transcript

  1. Status of the LHC Project L.Evans - C.Wyss Riunione CSN1 INFN Napoli, 21 Settembre 2005

  2. Beam parameters obtained from the central frequency measurements, averaged over the data obtained from the horizontal and vertical planes.

  3. Results of TI8 test

  4. End of civil engineering works in Point 5 (1st February 2005)

  5. Superconducting cable 1

  6. Superconducting cable 2

  7. Dipole cold masses

  8. Number of quenches to reach 8,33 Tat the first cooldown (560 dipoles)

  9. LHC Dipoles: integrated field

  10. Dipole field quality: average b3

  11. Arc quadrupole cold masses

  12. MSCB sextupole dipole correctors

  13. Cryodipole overview

  14. SSS overview

  15. Magnet Installation • Installation is progressing in sectors 8-1 and 4-5. More than 100 superconducting magnets have been installed. The installation rate must now ramp up to 20 magnets per week (16 dipoles and 4 SSSs) in the next few weeks. • At the end of October, sector 7-8 will be liberated for magnetic installation. From then on there will be no shortage of slots.

  16. First cryodipole lowered on 7 March 2005

  17. First SSS lowered on 19 April 2005

  18. Transport in the tunnel with an optical guided vehicle

  19. Transfer on jacks

  20. Preparation of interconnect

  21. Interconnection of beam tubes

  22. Interconnect in sector 8-1: in progress in sub-sectors C and F

  23. Pre-assembly of first low-beta triplet (hall 181)

  24. UA47: Quench protection & Power converters

  25. Cryogenics overview

  26. 2400 W @ 1,8 K in the UX85 cavern

  27. Repair of QRL modules

  28. Repair of special QRL elements at CERN

  29. Cryogenic distribution line

  30. QRL

  31. Reinstallation of QRL in 7-8 • Sub-sectors A and B (600 m) have been cooled down on Wednesday 14th September. • After the cold tests, the inner triplet will be installed, cooled down and powered whilst the rest of the line is being installed.

  32. First cooldown of 600 m cryogenic LHC line sector 13-14 September 2005 He out Th.screen line LHe line Pump. line He in 20 K line

  33. Conclusions • Main objectives: • terminate installation in February 2007 • first collisions in summer 2007 • The industrial production of standard components is compatible with this objective. • The ramping up of QRL activities and magnet installation is critical to maintain this schedule. • Additional actions have been implemented to ensure proper QRL production and installation rates. • The installation and interconnection of cryomagnets have started in the tunnel. • The commissioning of technical systems will take place in two adjacent sectors in parallel. • Main next actions: • partial test of sector 7-8 in autumn 2005 • commissioning test of the two first sectors (7-8 and 8-1) in summer 2006 • find external collaborators to help with commissioning. => many thanks to INFN for its support !
