TS-MME WORKPACKAGES Presented by V. Vuillemin/TS-MME .Abstract TS-MME holds two main workpackages in collaboration with the AB Department: - Beam Instrumentation - Collimators BEAM INSTRUMENTATION The beam instrumentation workpackage (WP) concerns the beam diagnostics elements required for the first LHC beam operations. This WP comprises: • Design studies. • Manufacturing drawings. • Construction and some assembly work of the beam instrumentation elements, except for some BPM's and the BLM's (CECOM/BINP), either directly in the main assembly workshop or by outsourcing some mechanical construction to external industries. The coordination managed by TS-IC of the installation in the tunnel of the elements (except for BLM's) is also included in this global WP. The Table 1 describes the overall organisation of the WP. Table 1              Essentially all design work is either finished or nearly finished, except for the BQK and two BSRT elements, for which the design work has been scheduled later. Manufacturing drawings are well advanced and some designs have been already forwarded to the main CERN workshop for construction The Table 2 below summarizes the status of the design activities at the time of the Chamonix XV workshop. Table 2                       Below are shown interesting examples of the designs of the beam instrumentation elements:                Figure 1: Beam Current Transformer  Elements N (models) Study Details Construction AssemblyCold BPMs 144 100% 95% Cecom / BINP TS-MMEWarm BPMs 24 100% 95% Cecom / BINP TS-MMEBPLX 2 100% 60%BPLH/V 12 100% 60%BPAWT 2 100% 60%BQK 4 0% (start février 2006) 0%Support BPM 6 100% 80% OutsourcedBLM 100% 100% RussiaBCT (ring point 4) 2 lignes 4 transfos / ligne 100% 100% TS-MME AB-BDI, AT-VACBCT(dump point 6) 2 lignes 2 transfos / ligne 100% 70% TS-MME AB-BDI, AT-VAC85% 85% TS-MME AB-DBIBSRTA, M, S 3 100% 100% TS-MME AB-DBIBSRTL 1 0% (start sept 2006) 0% TS-MME AB-DBIBSRTT 1 0% (start sept 2006) 0% TS-MME AB-DBIBWSH/V 1 100% 80% TS-MME AB-DBIBGIH/V 4 100% 100% TS-MME AB-DBIBTVSI 1 100% 100% RussiaBTVSS,ST, SE 3 100% 100% TS-MME AB-DBIBTVD 1 100% 100% TS-MME AB-DBIBTVDD 1 60% 0% TS-MME AB-DBIBTV (Profile TV screen Monitors)BGI (Profile Gas Ionisation Monitors)BWS (Profile Wire Scanners)BSRT (Profile Synchrotron Radiation Telescope)DESIGNBSRT (General study)BPM ( Beam Position Monitors)BCT (Current transformer monitors)BLM (Beam Loss Monitors) WP ORGANIZATION:Project Leader: C.Fischer / AB-BDICoordination between Departments: R.Garoby / AB-BDI, V.Vuillemin / TS-MMEDesign: WP owners C.Menot, A.Bouzoud / TS-MME + 11 designersDesign studies and manufacturing drawings for the>>Monitors:Beam Position Monitors BPMProfile TV Screen Monitors BTVProfile Gas Ionization Monitors BGIH/VProfile Wire Scanners BWSH/VBeam Loss Monitors BLMCurrent Transformer Monitors BCT[ BSRT, BGIH/V, BTV: 600 blueprints realized ]>>Profile Synchrotron Radiation Telescopes BSRTManufacture: WP owners J.P.Bacher, M.Polini / TS-MMEEstimated at least 3500 hours internal until mid-March, not totalAll except some BPM’s and BLM’sInstallation: TS-IC.

The priority in construction will be given to those parts of the elements that are connected to the LHC vacuum. Presently, up to mid-march 2006 (the WP is not yet complete) 3500 hours of construction and assembly have been scheduled in the main workshop, following the main LHC installation schedule. The most critical point is due to the fact that TS-MME has only one large folding press, with one expert technician. The press will have to work more than 8 hours/day in order to meet the production schedule. Table 3 below describes the present schedule in terms of construction, assembly and installation. A more precise scenario concerning the installation of the elements will be discussed in the beginning of 2006. Table 3                        COLLIMATORS The TS-MME WP owners are: A. Bertarelli, M. Mayer and R. Perret. This WP was defined already when the EST Division existed: "The EST provided output will be the required number of prototype collimators within the required schedule and drawings for the series production", namely the technical specification, the thermo-mechanical calculations, the design and drawings for series production as well as the production of 2 prototypes, including some testing. As the years have passed, the original requirements have gone through an evolution and the number of collimators/masks required have increased compared to what was defined at the beginning of the project. Including the prototypes, more than 1000 drawings have been realized in 2 years for 30 different variants and geometrical configurations, test benches and paloniers. The Table 4 summarizes the list of the collimators, masks and absorbers. All design work for the primary and secondary collimators (TCP and TCS) are finished and the production drawings have been delivered on time. The work on the masks has started with additional designers allocated to this task.

A new Research and Development WP for the Phase 2 LCH collimators has been accepted by TS-MME. Its aim is to develop a new secondary collimator concept and manufacture one or two full size prototypes in 2007-2008. However the present WP will cover only the development stage, namely: • Mechanical engineering, preliminary studies, thermal and mechanical calculations, new material research. • Test of materials, coatings, optimisation of vacuum, heat conductance coating. • Design and manufacture of test devices. • Functional tests. After the completion of the development stage, a prototype stage will follow to cover the detailed design for a prototype production, the handling of radioactive collimators and their new integration. CONCLUSION A large number of persons from the TS-MME group is working in an integrated way on these two WP's: 17-19 designers, 6-7 persons in the assembly workshop, as well as the project coordinators and engineers. All the specific technologies and know-how required for thin-film coating, brazing, welding, surface treatment and analysis as well as materials expertise and metrology, are provided by the TS-MME Group to complete successfully these two challenging LHC WP’s..
