1 A. Hervé - 13 august 2007 ILC-IRENG Meeting of Working Group A: 13 Aug 07 Proposal for an Experimental Area With only One Large Shaft A. Hervé/CERN

2 A. Hervé - 13 august 2007 ILC-IRENG Starting point On the suggestion of Andrei, we have looked at the possibility of having only one large 18 m shaft, plus another 9 m shaft. We have positioned these two shafts outside the footprint of the main underground hall to to do away with interferences between loading/unloading areas and working areas. This solution has been used for 3 of the 4 LEP experiments, Aleph, Delphi, Opal..

3 A. Hervé - 13 august 2007 ILC-IRENG Implications It necessitates horizontal transport from under the shafts to the experimental cavern, but this is not a problem for a full surface assembly scenario. The experiments are assembled underground on their own transport platform..

13 A. Hervé - 13 august 2007 ILC-IRENG Surface During 1st phase, there is only one large assembly halls for Exp A and Exp B, sharing three 80-ton cranes During second phase, there is a side hall covering the main shaft. One 80-ton crane is used there with a 12 m crane hook, reaching to half the main assembly hall. The main assembly hall is left witht two 80-ton cranes with a 19-m crane hook, allowing easing transfer of loads between the three cranes..
