17. IWAA2010 - R. BEUNARD – September 13-17, 2010 – DESY, Hamburg, Germany 17 The first solution which occurred to us is to transfer the beam Linac axis by optical plummet through this survey shaft. Installation the 2 nd order geodetic network Linac axis Pillar N°1 Pillar N°2 shaft longitudinal section of the Linac Lev. 0.0 m Lev. -9.50 m Filling up layer (calcareous stone extracted during the excavation) This solution was rejected because of the risk of neutron scattering at level 0 due to the difficulty to press down the calcareous stone around the shaft Transfer of aboveground coordinates into the tunnel via plumbing The beam line axis will be transferred onto the concrete slab from pillars 1 to 2
