Engineering Department EN Road Map for future Working

Engineering Department EN Road Map for future Working Group Activities A. Bertarelli, F. Carra, A. Dallocchio, N. Mariani, S. Redaelli 1 st Meeting Ad. Col. Mat Working Group 19. 08. 2013 19 August 2013 A. Dallocchio – CERN 1

Engineering Department EN 1. Propose an executive summary of the Hi. Rad. Mat tests results by identifying the main conclusions for future collimators with new materials. • • 19 August 2013 HRMT 14: collect, analyse and consolidate consistently test results • Recorder data (M. Guinchard + ? ) • FLUKA simulations (FLUKA Team) • FEM simulations (EN-MME, Polito) • Define, plan and follow-up post-irradiation campaign (CERN, BNL, PSI, …hot cell like ISOLDE…) HRMT 09: draw conclusions about this experiment focusing on the reliability of the numerical models. • Define, plan and follow-up post-irradiation campaign (CERN, BNL, PSI, …hot cell like ISOLDE…) • Assess consequences of material explosions on UHV, maintenance and operation (EN/STI, TE/VSC, BE/ABP, DGS/RP) A. Dallocchio– CERN 2

Engineering Department EN 2. Review/update nominal and accidental scenarios for all collimator families, for present and future LHC operating modes. • Collect existing nominal and accidental scenarios (Six. Track, FLUKA, FEM) for TCP, TCS, TCT…(next meeting talk(s)? ) • Update/define realistic nominal and accident cases (Six. Track, FLUKA, FEM) • 19 August 2013 • TCP and TCS: load cases taking into account recent operational experience and future upgrade programs • TCTs accident load cases consistently with outcome of the MPP Workshop…(next meeting talk(s)? ) On the bases of previous points, anticipate potential impacts on existing and future designs. A. Dallocchio– CERN 3

Engineering Department EN 3. R&D on Advanced Materials. • Review/ update material functional requirements to steer material R&D program…(next meeting talk(s)? ) • Rank the available materials with the aim of reducing the number of interesting candidates. • Suggest additional steps to improve material performances… • Prosecute with the development, industrialization and characterization of best material candidates. • Additional in-house test equipment to be acquired. • Acquire further experience from other experiments / tests 19 August 2013 A. Dallocchio– CERN 4

Engineering Department EN 4. Inputs for the design of future TCSx (next generation HLLHC Secondary Collimators). • Collect relevant functional/technical requirements for the LHC collimation system upgrade. • Propose optimum candidate materials for possible construction of new TCSx. • Collect requirements for RF system. 5. Executive summary of the Ad. Col. Mat WG. • If appropriate, propose the manufacturing of one or more TCSx prototype(s) for installation and test in the LHC or elsewhere after LS 1. • If appropriate, propose new material and device tests in Hi. Rad. Mat 2 as of 2014/15 (with upgraded measurement system). • If appropriate, propose ad-hoc tests on future prototypes for specific needs (maintenance, RF, …). 19 August 2013 A. Dallocchio– CERN 5

Engineering Department EN Next Meeting Talks: proposal • Collect existing nominal and accidental scenarios (Six. Track, FLUKA, FEM) for TCP, TCS, TCT. . . (more than 1 talk? ). • Review TCTs accident load cases consistently with outcome of the MPP Workshop. • Review/ update material functional requirements to steer material R&D program… 19 August 2013 A.
