Proposal to extend a contract to include work for the installation of the ATLAS Toroid magnets

This document concerns the proposal to extend an existing contract with the JOINT INSTITUTE OF NUCLEAR RESEARCH (JINR) (RU) to include the engineering and manufacturing of additional tooling and components as well as the provision of additional manpower needed for the installation of the ATLAS toroid magnets in the underground cavern. For the reasons explained in this document, the Finance Committee is invited to approve an increase of 1 468 000 Swiss francs, not subject to revision, in the previously authorised amount of 3 400 000 Swiss francs for an existing contract with the JINR. The cost of this work is to be covered by the ATLAS Common Fund. CERN's participation in the extension of this contract will not exceed 295 000 Swiss francs.
