Commissioning of the beam conditions monitor of the LHCb experiment at CERN

The LHCb experiment at CERN conditions monitor (BCM) consisting of 16 dia an active surface of 8mm × 8mm each, surrounding the beam pipe, in order to prevent the experiment from exposure to a possibly harmful LHC beam. It is based on a measurement of the current through these solid state detectors with an intergration time of 40 μs, so it provides the fastest input of LHCb to the beam interlock system. The current status of the commissioning is described in this work.
