  1. INSTALLATION OF LSS (Experimental insertions) S.Bartolomé - EDMS:547511

  2. OUTLINE • Critical case: sector 7-8 • LSS before installation of the beam line components • Provisional installation sequence of LSS8R (8-1) • Experimental insertions specificities • Summary S.Bartolomé - EDMS:547511

  3. LSS8L CRITICAL CASE: SECTOR 7-8 • Installation by CERN of the QRL in sector 7-8 gives the opportunity to: • Start with QRL sub-sector A and B (~600m left of point 8 (LSS8L)) in March 2005 and then, install magnets in parallel with the remaining of the QRL • Start QRL cold testing in June 2005 • Start installing magnets (LSS8L) in parallel with the remaining of the QRL in August 2005 • LSS8L cool down & power tests from October 2005 to March 2006 • Gather maximum experience on the field in 2005 with a view to propose an optimized and reliable scenario for the other sectors S.Bartolomé - EDMS:547511

  4. CRITICAL CASE: SECTOR 7-8 (cont.) • The following main diverse material have to be available for installation in Summer 2005: • Components: • Support jacks (supplied by CAT-India) • Motorised jacks for Inner Triplets: CAT-India jacks modified • Resistive magnets: MBXW and MBXWS • Inner Triplet (Q1-Q2-Q3) • DFBXG • D1-D2 • Collimator, TCL • Q4, Q5 • DFBMA/C S.Bartolomé - EDMS:547511

  5. CRITICAL CASE: SECTOR 7-8 (cont.) • Installation tooling such as: • Spreader beams for all magnets • Transportation system for DFBX • Vacuum equipment: • Cold-warm transitions (VAX, VAB,…) • Vacuum chambers • Supports • Beam position monitors (BPTX, BPMWB, BPMSW, BPMSX…) • Instrumentation • Others S.Bartolomé - EDMS:547511

  6. No-coactivity during power converters short circuit tests! No-coactivity during cool-down! Powering test possible co-activity with vacuum (bake-out and NEG activation) S.Bartolomé - EDMS:547511

  7. LSS BEFORE INSTALLATION OF THE BEAM LINE COMPONENTS • General requirements: • General services installed • Tunnel floor prepared for support jacks installation • QRL installed • DC cabling installed • Control and signal cabling installed • HLS (Hydrostatic Level System) and WPS (Wire Positioning System) preinstalled (where applicable) • And…where required: • Installation of transfer rails for Q1-Q2 installation (RB14, RB16, RB26, R542, R561, RB86) • Installation of shielding plugs (RPX24, RB26, RB84, RB86) S.Bartolomé - EDMS:547511

  8. LSS8R PROVISIONAL INSTALLATION SEQUENCE OF LSS8R (8-1) • Starting point: • QRL installation finished by June 2005 • QRL commissioning in August and September 2005 • Installation sequence of LSS8R: • Shielding in RB86 • Support jacks • Beam line elements installation: • Resistive magnet (MBXWS) • Inner Triplet and D1 • DFBXH • D2, Q4, Q5 • TCDD, TDI, MKI, MSI S.Bartolomé - EDMS:547511

  10. PROVISIONAL INSTALLATION SEQUENCE OF LSS8R(8-1) (cont.) • Alignment (Q1  Q5) • Magnets interconnection and closure (DFBX included) • DFBMA/C: transport and installation • Vacuum: • Install and connect components (Q1  Q5) • Install and connect standalone sectors (D2/Q4, Q5) • Install and connect components (warm sectors) • Reception, bake-out and NEG activation (warm sectors) • Power cables connections, signal cables, cooling and control components • Installation of survey equipment: HLS and WPS S.Bartolomé - EDMS:547511

DELSAUX 27/04/2004 QRL RB86 Shielding MBXWS RB 86 (28 April 2004) EXPERIMENTAL INSERTIONS SPECIFICITIES: IR8 • RB84: • Starting point: steel shielding installed • Standard installation of Inner Triplet  LSS transport vehicle and transfer tables • RB86: • Starting point: main part of shielding installed • Q1 installation: transfer with rails and motorised bogies S.Bartolomé - EDMS:547511

  13. RB14 Shielding UX 15 Holesfor Q1 motorised Jacks EXPERIMENTAL INSERTIONS SPECIFICITIES: IR1 • HLS and WPS preinstalled • Installation of steel-welded structure for continuing the rails and personnel access inside the ATLAS forward shielding tube TX1ST. • Installation of 2xQ1: transfer with rails and motorised bogies S.Bartolomé - EDMS:547511

  14. RPX24 EXPERIMENTAL INSERTIONS SPECIFICITIES: IR2 • RB24: • Starting point: RPX24 supporting structure and shielding installed PX24: used to lower down special magnets! S.Bartolomé - EDMS:547511

  15. EXPERIMENTAL INSERTIONS SPECIFICITIES: IR2 • RB26: • Starting point: main part of shielding installed • Installation of Q1 and Q2: transfer with rails and motorised bogies S.Bartolomé - EDMS:547511

  16. Point 5: Q1 located in UXC55 and R542/R561 CMS Shielding opening approx. 4x2x2(m) UPS galleries for alignment purposes EXPERIMENTAL INSERTIONS SPECIFICITIES: IR5 • HLS and WPS preinstalled • Installation of 2xQ1 and 2xQ2: transfer with rails and motorised bogies S.Bartolomé - EDMS:547511

  17. SUMMARY • Installation dates: • LSS8L  August 2005 • LSS8R  October 2005 • LSS1L  October 2005 • LSS5L  December 2005 • LSS5R  April 2006 • LSS2L  July 2006 • LSS1R  August 2006 • LSS2R  September 2006 • Each LSS is a particular case due to the specific configuration of the area and safety constraints such as: restriction on co-activities, on transports, on access during pressure tests, cold down and electrical tests. • A Schedule Change Request (SCR) will be required for each LSS.
