Description
At LHC the Beam Current Transformers (BCT) have an important role for machine
protection. The BCTs will be used to derive to important signals that will be
distributed with high reliability using the 'Safe LHC Parameter' system: the 'beam
presence' flag and the 'safe beam' flag. Both signals are derived from the measured
beam intensity in the LHC rings. This presentation will outline the present design
concept to provide reliable intensity information to the machine protection system.
Although the beam loss monitoring system will be the main instrument charged with
detecting and acting upon the majority of failures that could lead to quenches or
damage, a fast beam loss interlock using beam current transformers would increase the
overall reliability of the machine protection system. Requirements and ideas for the
realization of a fast loss interlock system based on BCTs will be discussed.
