    Vivien Rude (CERN)
    Monitoring
    Oral

    The low beta triplets quadrupoles magnets of the Large Hadron Collider (LHC) are located on both sides of the ATLAS, CMS, ALICE and LHCb experiments. The alignment tolerances of these components are particularly stringent (+/-0.5 mm at 3σ) and are tracked by an alignment system consisting of micrometric sensors and motorized jacks used for components remote displacements. The system has been...

  5. 38. ANALYSIS OF EARTHQUAKE EFFECT FOR BELLEII DETECTOR AND SUPERKEKB ACCELERATOR
    Hiroshi Yamaoka (KEK)
    Monitoring
    Oral

    Japan is the place of the most occurred earthquakes in the world. Displacement when earthquake occur is sometime gives damages to experimental devices or facilities. Although counter measures against earthquake are happened such as installing bellows at beam pipes or keeping some gap for clear earthquake shaking between the detectors, displacement due to an earthquake exceeds an allowable...

  6. 40. Stability Studies of High-Quality Concrete Slab Floors at the ESRF
    David Martin
    Monitoring
    Oral

    The ESRF machine and experiments require tremendous spatial and temporal stability. They are very often installed on concrete slabs so the stability of these slab surfaces is of paramount importance. Over a number of years, a large number of slab stability studies have been made in a number of different circumstances. We have found that after an initial drying period, slab movements are mainly...
