Description
Safe operation of the LHC requires coherence across several systems
for machine
protection: collimators and beam absorbers, beam dumping system, beam
monitoring,
beam interlocks, etc. Beam operation requires beam permit that can
only be
established when all LHC systems are ready for beam operation.
Extraction of beam
from the SPS and transfer to the LHC requires correct settings of the
extraction
and injection systems as well as the transfer line elements. When
operating with
beam, many different type of failures could lead to accidental beam
losses.
Failures are detected by the quench protection system and other
hardware related
equipment. Consequences of failures on the beam are detected by beam
loss monitors
and other beam instruments. This results in a beam dump request
transmitted via the
beam interlocks to the beam dumping system, that extracts the beam
into the dump
block.
The functionality of the LHC systems with respect to machine
protection is
presented. The overall strategy of the LHC machine protection is
discussed. Main
emphasis is on the interfaces and dependencies between the systems.
