  3. EN-EL interventions LS2 planning meeting • AUG on Monday 25 March 2019 - no access on site (both surface and underground) • Diesel maintenance: 1 Apr 2019 - Done • CERN wide 66kV maintenance: 28 May 2019 to 19 July 2019 – reduced consumption (i.e. no magnets) • Test secours (10 min): 19 Dec 2019 from 8:00 AM to 11:00 AM • 18kV, 3.3kV and LV network maintenance: • Mon 20 to Wed 22 Jan 2020: 3 days no general services - no access on site (both surface and underground) • Thu 23 to Fri 24 Jan 2020: 2 days ‘’Limited access’’  details being worked out • AUG on Monday 27 January 2020 - no access on site (both surface and underground) • Auto transfer test: 27-29 Apr 2020 • BIW test: 5 and 6 Oct 2020 from 18:00 to 00:00 – no access underground

  4. EN-CV interventions LS2 planning meeting • Big maintenance: • SF: from Nov 2019 to mid Jan 2020. NO impact on ALICE as both magnets will be OFF. • UW: stop UX mixed water for 2 days in week 40/2019 (October). • SU: various small perturbations + 1 day stop all cooling UX + 1 day stop all cooling SXL2 in week 16/2020 (April). • Small maintenance: • UW: from mid Aug 2020 to mid Sep 2020. Stop mixed water UXfor 1 day in week 37/2020 (September). • SF+SU: weeks 45-47/2020: cleaning towers (stop SF 1 week) + 1 day stop all cooling UX. • Ventilation: • SG2: w7/2019 - Done • Gas extraction: w8/2019 - Done • UX25 cavern: May 2020 (tbc) • MCH and MTG: Apr 2020 (tbc) • L3: Apr 2020 (tbc) • ITS: Apr 2020 (tbc) • Raw water: • Test after Apr 2019. Short interruption (1 day), can be used tap water during the test.
