HL-LHC-UK 2 § HL-LHC-UK is a collaboration of UK institutes and Universities delivering hardware for the High Luminosity Upgrade of the Large Hadron Collider at CERN. § The current collaboration, funded by STFC, has been successful in providing Research and Development into several key areas of the upgrade including; § Work Package 1 - Beam Dynamics (led by Manchester University) § Work Package 2 - Crab Cavities (STFC-Lancaster) § Work Package 3 - Beam Diagnostics (RHUL and Liverpool University) § Work Package 4 - Cold Powering (Southampton University). § In parallel the Laser Engineered Surface Structures (LESS) project has positioned the UK (Dundee University) as a leader in LESS technology for the mitigation of Secondary Electron Yield issues in the LHC. § LESS will join the HL-LHC-UK collaboration as WP 5 for the next phase of the project known as HL-LHC-UK 2. § The project will officially commence on the 1 st April 2020, with some pre-work ongoing in 19/20.

WP 2 Scope of Work Goal: Design and procure necessary components and then to assemble 4 Double Quarter Wave Crab Cavity Cryomodules Included; Review the design of pre-series cryomodule and undertake any design modifications. The procurement from industry of the required components to produce 4 cryomodules. Assembly of 4 x Double Quarter Wave cavity strings and associated ancillaries in ISO-4 clean room. Assembly of the cryomodules (cryostating). Undertake vacuum leak tests after thermal cycling with liquid nitrogen. Design and fabrication of the transport frame. Organise shipment of Cryomodules to CERN (CERN to fund). QA management for all the above. 18

WP 2 Scope of Work Excluded Design and procurement of cavities, tuners, HOMs, RF Couplers, RF Probes, beam line components and Cryogenic Safety equipment. Conducting Cryogenic and/or RF performance tests at 4 K and 2 K. The conditioning and testing of the RF input couplers (It is assumed that the conditioning and testing of the RF input couplers will be performed at and by CERN). Any-reprocessing of the cavities or RF Couplers in case of contamination at any stage between arrival, assembly and transport. Transportation costs from DL to CERN. Facilities The project will utilise the infrastructure developed for the RFD-prototype cryomodule located within ETC at Daresbury Laboratory. 19

WP 2 Scope of Work Assumptions STFC will share the efforts for design with CERN and University of Lancaster. The details of responsibilities have been agreed with CERN. Procurement responsibility will also be shared with the collaborators depending upon respective funding allocations. All required cryomodule drawings and CAD will be delivered by CERN to STFC upon project initiation. Assembly procedures for the cryomodule will be shared by CERN at timescales appropriate for the STFC project delivery. Drawings and/or CAD models for cryomodule assembly tooling will be made available to STFC by CERN at timescales appropriate for the STFC project delivery. Periodical review/progress meetings will be held with the collaborators. 20

Conclusions and further work • • 22 Progress is on schedule for RFD SPS Prototype assembly at Daresbury from Summer 2020. UK design responsibilities progressing well. Cold Shield designs complete, lessons learned from DQW SPS tests have been incorporated into Outer Magnetic Shield and thermal shield. Good progress on the transportation frame and internal transportation restraints working with CERN-UK need to finalise designs and begin negotiations with suppliers for Long Lead items (OVC and Cryogenic lines) • Orders to be placed for long lead items by end of September 2019. • HL-LHC-UK 2 proposal was submitted, to be reviewed in September 2019.
