Events leading to beam losses
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...

Events leading to beam losses
The beams in the LHC can be intercepted by many different types of
objects moving into the vacuum chambers. These include devices
designed for beam monitoring, machine protection and for data taking
by the experiments. Moving these objects can only be permitted under
certain conditions. Interlocks should prevent quenches or even
damage in case of wrong actions. An inventory of such...

Events leading to beam losses
The hardware parameters and the assumed operational scenarios of the
LHC tune and aperture kicker systems are presented. From this the
potential damage caused by the two systems is deduced. It is shown
that especially the aperture kicker can lead to significant damage
tot the LHC and an adequate interlock system is required. The
proposed combined hardware and software solution, which...
