Description
From the very start of LHC operations, the experiments will have a strong interest
in monitoring online the beam conditions and radiation levels in and around the
experimental areas. Although the equipment in these caverns is designed to tolerate
the expected radiation levels in normal operation, such monitoring is seen as key
to protecting the detectors from damage due to unexpected short- or long- term beam
losses, and necessary for understanding how beam conditions affect the efficient
operation of the experiments. This is especially important during the commissioning
and early running period of the LHC. As monitoring methods and equipment protection
concerns vary amongst the different experiments, this talk will address the general
issues associated with reliable beam and radiation monitoring within the
experimental areas and the estimation of beam loss and radiation damage in and
around the experimental areas. Varying time scales are to be considered, ranging
from ultra-fast beam loss, to run-by-run losses, to integrated long-term effects of
radiation. Specific examples of monitoring systems being implemented by experiments
will be given and implications for machine and experiment operations will be
highlighted.
