  A new generation of fast wire scanners is being developed for the LHC Injectors Upgrade (LIU) project at CERN. These will be essential tools for transverse profile measurement with the higher brightness LIU beams, and are planned for installation in 2019 in all three synchrotrons making up the LHC injector chain. An active period of development and test has resulted in prototype installations in the SPS and PSB rings. This paper will summarise the design and report on the results to-date.

  The Beam Gas Vertex detector (BGV) is an innovative beam profile monitor based on the reconstruction of beam-gas interaction vertices which is being developed as part of the High Luminosity LHC project. Tracks are identified using several planes of scintillating fibres, located outside the beam vacuum chamber and perpendicular to the beam axis. The gas pressure in the interaction volume is adjusted such as to provide an adequate trigger rate, without disturbing the beam. A BGV demonstrator monitoring one of the two LHC beams was fully installed and commissioned in 2016. First data and beam size measurements show that the complete detector and data acquisition system is operating as expected. The BGV operating parameters are now being optimised and the reconstruction algorithms developed to produce accurate and fast reconstruction on a CPU farm in order to provide real time beam profile measurements to the LHC operators.
