  1. Assembly Hall in Hybrid-A’ and ILD 2014/9/6 Yasuhiro Sugimoto

  2. Assembly hall for ILD • Five pieces of ILD yoke (YE-, YB-, YB0, YB+, YE+) are assembled in the surface assembly hall (AH) • Each yoke is assembled on the floor, and moved to a platform in AH by air-pads, and lowered to the underground detector hall after installation of some sub-detectors and magnetic field mapping • Muon detectors, solenoid coil, and barrel/endcap calorimeters are installed on surface (Trackers are installed underground)

  3. ILD requirement for AH • Space • ILD needs assembly space for 5 yoke rings and solenoid • If we assume 25mx10m space for each of YE± and YB±, and 25x20m for YB0 and solenoid, respectively, 25mx80m space is necessary • Crane • A 250 ton crane for yoke assembly and an 80 ton crane for solenoid/detector assembly and installation are needed • ~4000 ton gantry crane for detector lowering • Hall height • 22.6m from the floor to crane rail, 6m from crane rail to ceiling, plus alpha for lights and fans on the ceiling • Cryogenics • He gas pipes have to be connected from the compressor building for magnetic field mapping in AH • Platform • ILD should have its own platform on surface to avoid the risk of delay of SiD construction

  4. AH with a garage • AH should have a garage (alcove) for ILD to put 2 pieces (YE+, YB+) aside • This configuration gives several merits Garage

  5. Merits of AH with garage • Shorter AH • ILD assembly area: 80m65m • Flexibility of assembly area configuration, and effective use of 2 cranes • Preferable lowering order of ILD • YE-  YB-  YE+  YB+  YB0 is preferable, and can be achieved if we have a garage • YE-  YB-  YB0  YB+  YE+ might be OK if cryogenic apparatus on YB0 is small enough 80t crane has no task at this stage

  6. Lowering order of ILD • AH w/o garage YB- YB0 YB+ YE+ YE-

  7. Lowering order of ILD • AH w/o garage using SiD platform 1. Field mapping 4. YE+ Platform for ILD Platform for SiD 5. YB+ 2. YE- 3. YB- 6. YB0

  8. Lowering order of ILD • AH with a garage 1. Field mapping 4. YE+ 2. YE- 5. YB+ 3. YB- 6. YB0 YE+, YB+ step aside YB0 step back

  9. A possible design of AH • Plan view Compressor building 1st phase assembly hall for ILD 50m space between 2 assembly halls is required for VS/DH construction

  10. A possible design of AH • Side view

  11. Size of garage

  12. A possible ILD assembly scenario • Assumption • Similar timeline as Fig.14.10. in TDR Vol.3.II • Surface AH shown in the previous pages • Same assembly scenario of superconducting magnet as CMS; YB0  Outer Vacuum Tank (OVT)  Coil  Inner Vacuum Tank (IVT) OVT assembly Coil insertion IVT insertion

  13. A possible ILD assembly scenario 10 9 8 5 4 1 2 3 6 7 • Not ILD official timeline • Just a working assumption for the assembly space study

  14. A possible ILD assembly scenarioStep-1 Platform for ILD • Surface platform construction • YB0 assembly • Preparation for coil assembly Garage 250t crane 1st phase assembly hall 80t crane Swiveling platform for coil assembly

  15. Step-2 • YE+ assembly • Coil outer vacuum tank (OVT) assembly • Coil assembly

  16. Step-3 • YE- assembly • YE+ Muon detector installation • Inner vacuum tank (IVT) assembly • Coil assembly IVT

  17. Step-4 • YE- assembly • YE+ Calorimeter installation • IVT, Coil assembly

  18. Step-5 • YE- assembly • YE+ Calorimeter cabling • YB0 Muon detector installation • Coil assembly

  19. Step-6 • YB+ assembly • YE+ pushed into garage, ECAL cabling • YE- Muon detector installation • Coil assembly

  20. Step-7 • YB+ assembly • YE- Calorimeter installation • Coil, IVT installation  test for vacuum, cooling, and low current

  21. Step-8 • YB+ Muon detector installation • YB0 Calorimeter installation

  22. Step-9 • YB+ pushed into garage • YE- pushed to vertical shaft side • YB- assembly, Muon detector installation • YB0 Calorimeter installation

  23. Step-10 • Close detector • Field mapping (SiD is >50m away from ILD)

  24. Conclusion • AH with a garage has several merits for ILD • If AH can have a garage, ILD can be assembled with 65m (=52.5m+12.5m) length of AH (1st phase AH) • Total length of AH could be ~180m (65+50+65m) if SiD requires same length of assembly area
