MECHANICAL ENGINEERING OF ACCELERATOR COMPONENTS

This article provides an overview of the Mechanical Engineering of Accelerator Components by Antti Kolehmainen, Tommi Mikkola, and Tuukka Lehtinen on behalf of CERN. The group's mandate is to provide mechanical design, fabrication, and material sciences solutions to the CERN community. The article discusses material development, mechanical and geometrical measurements, engineering calculations, and production and sourcing processes. The deliverables, iterations, and workshops are also explained.

  1. MECHANICAL ENGINEERING OF ACCELERATOR COMPONENTS Antti Kolehmainen Tommi Mikkola Tuukka Lehtinen on behalf of CERN EN/MME

  2. CERN EN-MME GROUP “The mandate of the MME group is to provide to the CERN community specific engineering solutions combining mechanical design, fabrication and material sciences.” • We are around 150 people • We do: • Material development and mechanical and geometrical measurements • Engineering calculations and simulations • Mechanical design • Production and sourcing

  3. MECHANICAL DESIGN DESIGN INPUTS CLIENT SPECIFICATION FOR THE DEVICE AVAILABLE SPACE FOR THE DEVICE ALL PARTIES CONCERNED ARE INFORMED

  4. MECHANICAL DESIGN • DELIVERABLES: • 2D DRAWINGS • 3D MODELS • SUPPORT DOCUMENTS • ITERATIONS: • CLIENT • ANALYSIS • INTEGRATION • MANUFACTURING

  5. MATERIAL DEVELOPMENT AND MEASUREMENTS • MATERIAL DEVELOPMENT: • GRAPHITES FOR BEAM IMPACTS • STAINLESS STEEL ALLOY FOR PERMEABILITY • MECHANICAL MEASUREMENTS: • Non Destructive Test: X-RAY TESTS FOR THE LHC DIPOLE MAGNETS • Destructive Test: TENSILE TEST OF MATERIALS GEOMETRICAL MEASUREMENT OF COMPONENTS TO VERIFY COMPLIANCE TO THE SPECIFICATIONS

  6. ENGINEERING CALCULATIONS SAFETY ASSESMENT, GUIDES DESIGN WORK AND VERIFIES THAT A DESIGN MEETS ITS REQUIREMENTS BOUNDARY CONDITIONS FUNCTIONAL DEVICE ANALYSIS RESULTS

  7. PRODUCTION EN/MME HAS THREE WORKSHOPS • REMOVE MATERIAL BY CUTTING – ONLY METAL MATERIALS BY EN/MME • ADDING DEGREES OF FREEDOM ALLOWS MORE COMPLEXE GEOMETRIES • ELECTRICAL DISCHARGE MANUFACTURING – ELECTRICAL ARCS REMOVE MATERIAL • FORM MATERIAL • BEND / ROLL / DRAW • 3D PRINTING IN USE – AND IN CONSTANT DEVELOPMENT!

  8. PRODUCTION AND OUTSOURCING • PURCHASE SIMPLE COMPONENTS AND LARGE SERIES FROM INDUSTRY • WELDING • MELT THE PARTS TO BE JOINED LOCALLY – FILLER METAL MAY BE ADDED • BRAZING • JOINED PARTS DO NOT MELT, ONLY FILLER METAL. DIFFERENT MATERIALS CAN BE JOINED
