  1. MAIN STEPS OF CERN WORKS D. Tommasini

  2. DIPOLE TYPES • Cold mass assembly types (2 variants) • MBA: MB with sextupole, octupole and decapole • MBB: MB with sextupole • Diode installation types (2 variants) • AR : "Anode on the Right" • AL : "Anode on the Left" 4 DIPOLE TYPES IN INDUSTRY: AL, AR, BL, BR D. Tommasini

  3. DIPOLE TYPES • Dipole extremities for interconnect • ARCS : 4 interconnect variants 10 cryodipole types LBALA, LBALB, LBARA, LBARB, LBBLA, LBBLC, LBBLD, LBBRA, LBBRC, LBBRD • DS : 10 interconnect variants 24 cryodipole types LBALA, LBALE, LBARA, LBARE, LBARJ, LBARL, LBBLA, LBBLB, LBBLC, LBBLD, LBBLF, LBBLG, LBBLH, LBBLI, LBBRA, LBBRB, LBBRC, LBBRF, LBBRG, LBBRH, LBBRI, LBBRK, LBBRM, LBBRN 27 CRYODIPOLE TYPES FOR CERN See LHC-LBA-ES-0011.00 rev. 2.1 by Jean-Philippe Tock under approval D. Tommasini

  4. INSTALLATION ORDER AND DIODE POLARITY D. Tommasini

  5. INSTALLATION ORDER 4 6 5 7 2 1 R sector 8 3 L sector Installation order 4 D. Tommasini

  6. INSTALLATION From the middle of the arc to dispersion suppressor : Q34, Q33, Q32… ….Q9, Q8 D. Tommasini

  7. EXAMPLES • ARC … … • DS … …….. … D. Tommasini

  8. FLAGS Three different flags (to be discussed in MEB) can be installed anywhere not close to a red flag – or specified period must have a specific and appropriate location D. Tommasini

  9. CRYODIPOLES STORAGE CRYODIPOLES STORAGE SITE PREVESSIN D. Tommasini

  10. CRYODIPOLES STORAGE FUTURE DIPOLE STORAGE ZONE FUTURE ACCESS ROAD Prévessin dipoles storage site • Maximum capacity :  120 cryodipoles • Dimensions :  185 m  30 m D. Tommasini

  11. CRYODIPOLES WORKS 1232 110 10 27 35 35 60 25 D. Tommasini

  12. RATES D. Tommasini

  13. CONCLUSION • installation will start beginning 2004 • sorting limited to special cases only (more freedom for first octant) • a 30 magnets buffer in zone 18 for special cases is probably necessary • MEB decisions shall be taken  one week days after fiducialization • depending on flag a magnet will be assigned to a specific location • most of magnets shall be green D. Tommasini
