Description
A diluter block TCDQ, with a collimator TCS and shield TCDQM, will be
installed in front of the superconducting quadrupole Q4 magnet in
IR6, to protect it and other downstream LHC machine elements from an
unsynchronised beam dump. The system should also intercept particles
in the abort gap to prevent quenches during regular aborts, and must
also intercept the particles from the secondary halo during low beam
lifetime without provoking quenches. The conceptual design of the
system is briefly presented, and the FLUKA energy deposition
simulations described. The results are discussed in the context of
the expected performance levels for LHC operation, in particular for
the problems associated with quenches. Options for improvement are
elucidated and required future work is defined.
