Description
Good orbit control is very critical for the LHC due to the tight aperture at
injection and the stringent orbit stability constraints from collimators and
absorbers. A real-time orbit feedback system will be used to ensure adequate orbit
stability during all operational phases. While the orbit feedback is important for
operational efficiency, it cannot be used for machine protection directly. An
interlock system based on redundant beam position monitors located around the beam
dump extraction elements will be used to protect the beam dump channel from damage to
due excessive orbit offsets. The same system will also provide an interlock signal
for fast orbit drifts. The position interlock system will be discussed, in particular
the complementary protection they provide to the beam loss monitoring system.
