Cryomodule assembly platform

Rolling of the cavity train out of the clean room


1650 m2 cryomodule assembly halls with 3 cranes (m ≤ 20 t).



Technical means

Large halls dedicated to cryomodule assembly including :

  • Clean room exit area (A = 16x7.5 m2, ceiling height h = 12 m),
  • Alignment area (A = 17.5x16 m2, ceiling height h = 12 m),
  • Cantilever area (A = 40x11 m2),
  • Shipment area (A = 30x17 m2),
  • Warehouse (A = 25x12 m2, on two levels).


Additional facilities :

  • Gas distribution network (air, He, Ar),
  • 1 electric forklift truck capable of handling loads of mass m  20 T.


One could set up different workstations on this platform.

Achievements, related projects

This cryomodule assembly platform was built on the premises of the former Saturne Synchrotron to host the XFEL project from 2008, and was then used in the framework of this project for the assembly of 103 cryomodules (from the clean room exit to the cryomodule shipment).
