Run III
HL-LHC
(April 2016) Collimator gaps calculated using baseline
settings. Where settings are still under discussion, the most
pessimistic (closest) setting is assumed. This is in particular the
case for the TCLs in the squeeze (assuming here that, regardless of
beta*, they stay at their innermost setting adpated for 15 cm), for the
TCLDs (assuming here that they are at the same level as the IR7 TCLAs)
and the TCT6 (assuming here that they are at the same opening as TCT4).
