  • assess the duration of the individual steps and define a realistic schedule for the series production
  • learn the transfer of the C-frames between the various frames and cages

Purpose of the Prototype C-Frame

The purpose of the prototype is to answer many of the following questions to prevent critical errors and excessive delays in the serial production of the 12 C-Frames to be installed in LHCb in 2019-2020.

The Prototype SciFi C-Frame

The List of Prototype C-Frame Parts

  1. Full structural mechanics (I-beams and mounting plates), Plan A (extruded) and Plan B (assembled)
  2. Steel wires (maybe carbon fibre) for hanging the bottom sub-assembly
  3. Novec Collars
  4. Novec Manifold with connections for at least 2 cold boxes with distribution lines on the C-Frames (everything for a functional system)
  5. Cabling on one side (stereo) plus cables for two X-side modules
  6. Water Cooling blocks plus pipes (2 different types from multiple manufacturers) includes a set for the top X and U, and for the bottom X and U. Distribution pipes are also needed.
  7. Dry gas flushing (investigate integration). A temporary solution may only be possible.
  8. A minimum of 2 Stereo- and 2 X-Modules with cold boxes loaded with SiPMs; 10 modules without cold-boxes to check module deformation
  9. A carbon-fibre bar to test improving the stiffness of the modules by joining the stereo and X-layer together.
  10. Two functional front end Boxes

  • ­What is connected in what order?
  • ­Can things be done out of order?
  • ­What tools are needed at each step?
  • ­Do we have access to the connections at this step?
  • ­Find the logical mistakes.
  • ­Is alignment needed?
  • ­What can be easily damaged and requires protection?
  • ­What can be performed in parallel in the serial production?
  • What are we checking or measuring at each step? ­Tolerances, deformations, etc?
  • ­What do we need to measure or evaluate at each step? Survey?
  • What happens if a part isn’t fitting/working/available? ­Do we reproduce it for the prototype? Or just boot-strap it on. ­Case by case basis
