MRV system budget and scheduling Short overview installation Dr. Marcelo juni Ferreira ESS Vacuum Section Leader European Spallation Source ERIC 28/05/2019

Outline Background of ESS monolith solution, Introduction to ESS Vacuum System, Vacuum Standardization Vacuum requirements: TARGET Monolith Rough Vacuum System specifications and interfaces,

ESS Monolith Vacuum System Brief history: cost/budged April/2014 Cost/budged was planned as He solution only (pump/purge). Jun/2017 Service Level Agreement Vac-TARGET Div. for the Monolith Vacuum system solution Feb/2019 Formal responsibility transfer of the Monolith Rough Vacuum System to the ESS Vacuum Section on the original cost/budged from He solution (≈ 1.1 M€ no-labor only), May/2019 Monolith Rough Vacuum CDR (alignment of scope for Vacuum Section responsibilities)

Early schedule for Monolith installation Only high level milestone available from P6 First time we need vacuum tests during installation of monolith 7th of Feb 2020. - Leak test of the Proton Beam Vessel Monolith rough vacuum system fully functional (System test performed), 1st march 2022 - First pump down fully loaded and leak tested

Top view Dec -19 (Temp crane op.) Temp crane 65 ton

Monolith Vessel installation Access route for portblock installation

High bay Crane for Target installation period Preferred solution 2 x 65 Ton Temporary cranes Temp. crane 65 ton Operational jan -20 Temp. crane 65 ton Operational dec -19 Or Permanent crane 95ton Cleanliness during installation inside monolith (same requirements for temp. Crane as for permanent crane) Speed (traverse and hoist) suitable for installing heavy sensitive components True vertical lift (might not be a requirement for temp. crane, Allow to have parallel work on both area (building won’t be fully close during the installation inside monolith)
