LS1 planning meeting

15.8.2013

Comments on LS1 schedule

• Schedule reviewed last week with Yann + TC… sequence after OD looked too squeezed therefore DCal SM installation delayed by one week (Joseph informed)

• Issues:– DCal installation DCal phone meeting 3rd September (tbc)– TRD SM insertion Bernd says realistically speaking we will have only three

SMs during LS1.– TOF slot depending on:

• Date completion LV modification BKF• Availability all rails (Yannick) + installation (10 SM must be moved)

• I hope we can finalize these details by beginning September.

Rain - actions• Coming two weeks: GS to contact TSO in order to establish action

plan in case of rain • SXS2: roof inspected and cleaned last week (GS)• >>> ACR: GS will move pipe outside SX2 building <<<• P2: Vallier has intervened this week to clean both foul and rain

water networks now regular cleaning• Long term: modify and repair the P2 drainage network
