  For two years (Spring 2013 - Spring 2015), the LHC went through its first long shut­down (LS1). It was mainly mo­ti­vated by the con­sol­i­da­tion of mag­net in­ter­con­nects, to allow op­er­a­tion with 6.5 TeV pro­ton beams. More­over, around the ac­cel­er­a­tor com­plex, many other sys­tems were re­paired, con­sol­i­dated or up­graded, and sev­eral new in­stal­la­tions came to life. The stan­dard­iza­tion of vac­uum con­trols has pro­gressed in the in­jec­tors, with the ren­o­va­tion of most of their ob­so­lete equip­ment. In the LHC, many new in­stru­ments were added, the sig­nal trans­mis­sion in­tegrity was im­proved, and the ex­po­sure to ra­di­a­tion was re­duced in crit­i­cal places. Sev­eral de­vel­op­ments were needed for new equip­ment types or new op­er­a­tional re­quire­ments.
