438 blocks910 tons !
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

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
Consequences of more LEP yokes
F. Butin / ELENA collaboration
Loses main access
Secondary accessremains

Takes a lot of space !

Aegis 2
Big impact onASACUSA laser hut
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

Main questions to GBAR
Detailed installation schedule ? Confirm interface with LNE50
transfer line (see drawing AD_LM_0083and AD_LM_0077)

Please check Catia modelWith O. Choisnet !
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 (…)
