11. La particularité du bat 193 ne permet pas un accès aisé et rapide pour les livraisons (seule une petite partie des remorques est accessible avec le crochet du PR 591 (zonage orangé). De plus, le stockage sur place est très limité, ce qui implique une réalisation en flux tendu… Livraison des 438 blocs nécessaires :  ~3 semaines/3 personnes -> 2.25 FTE/mois En recouvrement pour une partie Réalisation du blindage :  ~3 semaines/3 personnes -> 2.25 FTE/mois 1 FTE/mois = 8100 CHF soit 4.5 * 8100 = 36450 CHF (courtesy S.

12. Alternative with more LEP yokes F. Butin / ELENA collaboration

13. Alternative with more LEP yokes F. Butin / ELENA collaboration Cost cut by about factor 2 Not validated by RP yet Known to have issues Suppresses main access

14. Consequences of more LEP yokes F. Butin / ELENA collaboration Loses main access Secondary access remains OK with safety rules

15. Takes a lot of space ! F. Butin / ELENA collaboration Aegis 2 Big impact on ASACUSA laser hut

16. Time scale All bunker blocks are available at CERN Booking ASAP, when financing is secured Start blocks transfer and assembly in AD hall ASAP (impact on AD): 16th November 2015 Simultaneous assembly estimated to last 4 weeks: could be finished by end 2015 Rest of shielding installation (exp area) + laser barracks depends on GBAR schedule F.

18. Main questions to GBAR Detailed installation schedule ? Confirm interface with LNE50 transfer line (see drawing AD_LM_0083 and AD_LM_0077) F. Butin / ELENA collaboration Please check Catia model With O. Choisnet !

19. Main questions to GBAR (2) Updated experiment layout Catia model Estimates of ozone release Number, position and types of power sockets to be installed Negociate with PH a location at CERN for more storage ! Come to a conclusion on Linac shielding (…) F. Butin / ELENA collaboration
