Description

The beam gas vertex detector (BGV) is a beam profile monitor at the Large Hadron Collider (LHC). It is based on a technique that was pioneered in the LHCb experiment where charged particles produced in inelastic beam-gas interactions are used to reconstruct beam-gas vertices and obtain the transverse beam shape. This non-destructive method allows the measurement of additional beam properties, like position, tilt and relative bunch populations, throughout the complete LHC cycle. A BGV demonstrator device using scintillating fibre detectors read out with silicon photomultipliers was installed in LHC Ring 2 in 2015. We present an overview of the project and report first results from the commissioning in 2016.
