LBNF - Required infrastructure to start cryostat installation and material movement Dimitar MLADENOV & The entire CERN Team FS Installation Workshop SURF, 19-22 August 2019
LBNF Required infrastructure to start cryostat installation At T0 we would need: Access (both sides) If a permanent one is not available (the preferred option), then we need temporary one (stairs, scaffolding, Alimak, etc.) Lights If a permanent one is not available (the preferred option), then we need temporary one. In the cage? Electrical Power Single and three Phases, US as well as EU Communication WiFi, GSM?, Ventilation Shall be operational Compressed Air Could be temporary Working Safety Organization Training, approved PPE, requirements, access control, etc. Full Organization on the Surface for lowering down the material All the beams for the floor shall be ready for immediately availability Underground Crane & Hoists Shall be operational (including a professional rigging team, and full set of basic rigging accessories) Fully operational survey team General cleaning, by dedicated team will be performed on daily bases Also to decide who provides some of the tools Load guiders for the shafts Carts for the beams Etc.
