By Beniamino Di Girolamo (CERN)

The 8th HL-LHC Collaboration Board took place during the last HL-LHC Annual Meeting in October 2018 at CERN.

During the last months, several collaboration agreements have been prepared and are in the process of signature or advanced stage of finalization.

- INFN for the production of the D2 cold masses. INFN is finalizing prototypes and models of the D2 cold masses and ready to start production. The signature of the agreement will happen this summer.

- The Republic of Serbia, now CERN member state, proposed a special 100% in-kind contribution for the magnets, crab cavities and TAXN jacks. The collaboration agreement is in preparation.

- The Russian Federation will contribute several items for the project and for CERN; seven agreements with the Budker Institute (BINP) in Novosibirsk have been prepared concerning:

  • The manufacturing of the TAXS and TAXN absorbers for IR1 and IR5
  • The manufacturing and testing of the RF Solid State Power Amplifiers
  • The manufacturing of the Collimators mechanics
  • The manufacturing and testing of High Current Leads
  • The manufacturing of the BPM mechanics
  • The manufacturing of elements of the LHC Dump System
  • The manufacturing of elements of the Hollow Electron Lens

The first two were signed at a CERN-Russia meeting in April. One agreement has been prepared for the manufacturing and testing of the BLMs with IHEP Protvino, part of the National Research Center Kurchatov Institute, and finally an agreement for the manufacturing of the mechanics of the Crystal Collimation System with PNPI Saint Petersburg and IHEP Protvino, both part of the National Research Center Kurchatov Institute.

- A collaboration agreement for the manufacturing of the DFHX and DFHM cold boxes is being negotiated with the University of Uppsala.

- UK collaborators have submitted funding requests for collaborations for the construction of: crab cavities cryo-modules, DFX/M cold boxes, beam instrumentation devices and further development of the LESS surface structuring of beam screens.

- The CIEMAT agreement of the production of the nested correctors was signed in 2019.

Additional discussions are ongoing with a number of Institutes to establish other possible smaller collaborations as the list of opportunities is becoming close to empty.

The following table shows the status of signatures of MoUs and Collaboration Agreements per Institute.
