Future topics: HL-LHC PLC -Review of the HL-LHC Layout in the insertions We could cover perhaps two IRs in one meeting TAS & TAN space, space for additional components (e. g. Octupoles) -IR layout with CC -Vacuum beam pipes for experiments and report from LEB -Required corrector circuits required octupole strength triplet corrector package -Generation of a common Glossary with the experiments (Availability, efficiency, Turnaround time, pile-up etc. ) -DS collimators -Places for higher harmonic RF system and new BI 1 st HL-LHC PLC Meeting 3 rd July 2012 Oliver Brüning BE-ABP 8

HL-LHC PLC Future meetings: -Regularity of the PLC meeting once per month to start with? should we aim at another meeting before summer? -Time slot confirmation Tuesday mornings from Doodle? 1 st HL-LHC PLC Meeting 3 rd July 2012 Oliver Brüning BE-ABP 9
