Temporary warm line for sector test Volker Mertens, LHC-TCC, 21. 9. 2001 Outline: Situation Assumptions / constraints Status of injection elements (MSI, MKI, TDI/TCDD) Temporary optics Magnets Other components + services Planning Summary

  2. Situation UX85 centre IP8 ~ 215 m to substitute bxbyDx

  3. Assumptions / constraints • Substitute definitive LHC part between MSIs and triplet left of IP8 • Install definitive injection elements (MSI, MKI, TDI/TCDD - as far as available) • Reproduce basic geometry and optics around MSI - MKI - TDI to set up + test injection under real conditions • Match to TI 8 and 8-7 arc optics • Do not require triplet powering • Install definitive vacuum elements and instrumentation (where reasonable + available) • Use elements foreseen for TI 2 (+ SPS spares) to fill the holes (magnets, vacuum, instrumentation, p. converters) • Find (keep) space in UA87 (+ UA83 ?) to locate power converters • Pull short cables (e.g. through holes between UA87 and RA87) • LHCb magnet in place, remainder of UX85 covered by solid platform • Avoid unnecessary costs

  4. Injection septa (MSIA/B) IHEP / Protvino MSIB pre-series magnet at CERN • 2/3 of series produced

  6. Injection kicker (MKI) layout Beam RA87 MKIs UA87 PFNs MKI PFN J. Grieger / EST

  7. MKI prototype magnet magnet inside LEP separator tank mounting of matching capacitors

  8. MKI prototype magnet • prototype assembly + tests  10/01 • series construction  12/02 • series tests  04/03 • finished  10/03

  9. Injection stopper (TDI) design side views absorber beam view • design  ~12/01 • finished  ~06/03 V. Maire / EST

  14. UA87 cross sections (normal injection elements) MSI MKI

  15. UA87 cross sections (temporary elements) B280 QTL No obvious problems, but this does not replace a detailed integration study  MIWG / ICL

  16. Area around RA87 / UA87 (principle) MKI RA87 PFN UA87 power converters ? details (placement of converters + cabling paths) to be studied  PIWG MSI transformer + switchboard CDD LHCEY___8004 source: J. C. Guillaume / ST

  17. Area around UX85 (principle) only LHCb magnet in place power converters ?

  18. UX85 with LHCb magnet and “half” platform principle shown; details to be checked: e.g. behaviour of platform under emergency breaking with load maquette KR082007PL R. Valbuena + D. Parchet / EST

  19. UX85 with LHCb magnet and “half” platform principle shown, details to be worked out, e.g. vacuum supports, in part. at magnet crossing R. Valbuena + D. Parchet / EST

  20. Connectivity to triplet on left side of IP8 preliminary sector 8-7 > < IP8 detailed hand-over point to be agreed as function of availability of components maquette BP502066PL source: R. Veness / LHC

  21. Some more info on equipment (prelim.) + open points This is the starting point … detailed layouts to be studied ... Vacuum: • Install definitive part for and around MSI - MKI - TDI/TCDD. • Fill up straight sections with TI 2 material (60/63 mm) (check for supports). • Increase pumping to 1 VPIA / ~ 15 m (TI 8: 1 VPIA / ~ 60 m). • Put 1 - 2 400 l pumps before entry of cold section. • Put temporary power supplies + controls in UA87. • Part bridging LHCb magnet only to be put up shortly before the sector test. Power converters / AC supply / cabling: • Baseline assumption: install converters in UA87 (+ UA83 ?) (SR8 pretty full) • Clarify rating + availability of transformer + switchboard (ERD1/87). Cooling: • Baseline assumption: draw from the available pipeline, using flexible hoses. • Clarify availability of IP8 water station (normally ok by that time).

  22. sector 8-7 Overall planning: 2004 2004 2003 LHC side installation of warm line dismantling of warm line TI 8 SPS side

  23. model B: 2 t model A: 22 t Further provisions for sector test: temporary beam dump • have temporary beam dump at end of arc • choose model / dump performance according integrated + instantaneous intensities (to be specified) • mind INB regulations: containment, zoning, intensities logging, ...

  24. Summary Substitute for sector test LHC part between MSIs and triplet left of IP8. Baseline assumptions: • Install definitive injection elements (MSI, MKI, TDI/TCDD with their associated vacuum + instrumentation; certain surrogates are possible). • Reproduce basic geometry and optics around MSI - MKI - TDI to set up + test definitive injection choice of elements. • Holes mainly to be filled up “à la TI 8” (material mainly to be “borrowed” from TI 2) (magnets, vacuum, instrumentation). • Candidates for active components found (magnets, power converters). • Many details need still to be worked out (proper integration study, exact location of power converters, cabling paths, location of controls equipment, pumping scheme, BI + vacuum integration, vacuum across LHCb magnet, …). • Specify performance of temporary beam dump at the end of the arc (INB !). • Planning should not pose particular problems (once TI 8 is (success)fully installed).
