Description
The most likely reason for the loss of the circulating beam is an
incorrect magnetic field in one or more magnets. In this
presentation a catalogue of failures in the magnet powering system
will be presented, and the time constant for beam loss will be
discussed. Most likely are quenches in the superconducting magnets,
in particular at 7 TeV. Other failures are the discharge of magnets
with a resistance in the circuit (after a quench, or due to a
failure), a trip of magnet power converter, failure in the power
converter controls system. An electric short in the coil of a normal
conducting magnet has also been considered.
