Abstract
| The extensive array of beam instrumentation with which the LHC is equippedhas played a major role in its commissioning, rapid intensity ramp-up and safeand reliable operation. Much of this equipment will need consolidation by thetime the LHC enters the High Luminosity (HL) era while the upgrade itselfbrings a number of new challenges that are currently being addressed.Installation of a completely new final focus system in the two high-luminosity LHC insertions implies the development of new beam positionmonitors to equip the upgraded quadrupole magnets. In addition to replacingthe current directive stripline beam position monitors, which allow indepen-dent measurement of both beams in a single aperture, eight additional beamposition monitors will be added per interaction region, to further improve beamcontrol at the collision point. |
