It will be the only instrument capable of non-invasive beam size measurement throughout the LHC acceleration cycle with high intensity physics beams. A prototype BGV monitor has been installed in the LHC since 2016. Particles emerging from beam-gas interactions are recorded by 2 planes of scintillating fibre detectors. Based on vertex reconstruction of the detected tracks, this monitor allows non-invasive measurement of beam profiles with bunch-by-bunch resolution. A dedicated computer farm performs track reconstruction and event analysis on-line so that real-time beam profile measurements can be provided. Data taken in 2016 and 2017 will be presented that demonstrate the power of the method.
