Design Updates (Nicolas and all) + priorities definition

• New radii for UHV flange: 4x 3D models to update

  • type A and D2 to be done

  • type B is done

• Absorber covers: 3D still ongoing

  • springs fixation preliminary design done

  • more detailed 3D will be available --> action Nicolas

  • spring properties to be checked with supplier (Feuerherdt) --> action Gerhard

• Cooling tubes length

  • implemented already on tubes parts (assemblies and 2D drawings to be updated) --> will be completed before the review, action Nicolas

• Transition for D2

  • following the BS modification, transitions to be modified, 3D done, 2D done, action close

  • Michal confirmed to Nico Kos that BPM change has been completed (action for BI in ECR)

• New Reinforcement supports (4 designs)

  • 3D for 4 types done

  • 2D for two types done

• Modification of main body A for cooling reinforcement

  • 3D done, 2D to be done

• New Feedthrough for D2

  • waiting for next iteration (drawing to be released asap, waiting for the next iteration from procurement process feedback)

• Update of D2 main body external dimension (140->130mm) + inner changes

  • 3D done, 2D to be done (maybe already done, to be checked --> Nicolas)

• Welding machines integration study

  • drawings exist for Type B (ready by Friday evening --> Nicolas)

  • drawings and 3D for Type A --> to be checked

  • D2 --> 3D and 2D

  • hide all the non-completed parts from integration models --> action Nicolas, this was agreed with Delio

    • 3D views with welding machines to be prepared for the review --> action Nicolas

• Comments on Heeral test bench

    • low priority
