Updated infrastructure intervention schedule .... • Muon cooling station maintenance • Side A: March 6 to 7 (shifted). All muon power off. – Impact on TGC HV tests ? • Side C: March 8 to 11 (shifted). All muon power off. • Consolidation and pipe replacement for Mixed Water (EM)/Chilled Water (EG) • Backup connection from SUX1 EM/EG: Mar 4 to 8 (unchanged) – cuts of US15 rack cooling circuit, racks on HS US15 side level 7/8, MDT, RPC off. • Backup connection from SU1 EM/EG: Mar 11 to 15 (unchanged): -- cuts both muon cooling stations, all detector power off. • Sectorisation of chilled water (cut chilled and mixed water US15): April 15 to 19, new. – Impact on EE commissioning ? • From a safety point of view, running 48V, HV, LV for EE is not a problem, however until the revised DSS matrix approved in Dec is deployed there is a DSS interlock on the full MDT system …
