Description
The LHC beam loss monitoring system is designed to protect the equipment against
damage and quenches caused by lost protons. Proton initiated secondary shower
particles are detected by ionisation chambers and secondary emission detectors
located outside of the cryostat. The measured shower intensities are compared with
energy and loss duration depending quench level values and a signal is generated if
thresholds are exceeded. A single monitor will be sufficient to generate this beam
aboard signal.
A summary of the system specification will be given and its implementation will be
shown. Parameters characterising the expected and measured system performance will be
discussed and the beam loss detection possibilities in the LHC collimation areas will
be reviewed.
