1 Remaining LHCb related tasks during LS1 with DT involvement LHCb/DT meeting, May 19, 2014

2 VELO and Muon detectors VELO: replacement VELO needs to be brought in a safe position while heavywork is done in the surface building from June onwards. Muon: Work on chambers to improve the grounding (carried out by Nikolai), is to 90 % done. Two GEM chamber in M1 need still to be replaced (by INFN colleagues). Detector closing and alignment is a major effort. Preparations for the installation of additional shielding under HCAL need to carried out before the summer, in close consultation with our colleagues working on the calorimeters.

3 Calorimeter Consolidation of calorimeter moving system before end of June with Annecy colleagues as main actors, but Robert will assist them. – Remplacement des soufflets des vis a billes SPD cote A et C et alignement. – Remplacement des soufflets des vis a billes ECAL cote A et alignement – Installation d'un systeme de fermeture des portillons des plateformes ECAL et HCAL cote A et C et passage des cables – Reparation du end switch HCAL cote C (remplacement et passage de nouveaus cables) – Cablage, controle et mise en fonctionnement des nouvelles protections (end-switch, fermeture portillons) – Mise a niveau du systeme de commande et de l'armoire de controle des deplacements ECAL/HCAL. In addition about 2 ½ days are needed for calorimeter movements, about ½ day per week.

4 HERSCHEL (FSC) Installation of 5 Forward Shower Counters (FSC) stations (4 scintillation counters per station) in the LHC tunnel before the cool-down of sectors78 and 81.  Installation should be done in August. Preparation of mechanics done with PNPI technician. Installation of cables for the counters, including supports and holes to pass through the cables.  Should be finished by June 15.
