C.MADEC - TTC meeting Infrastructures ready

C.MADEC - TTC meeting Clean room tools –Cavity post: Height = 1050 mm –Alignment tool : Post constraint Adaptation –Cavity cart for coupler assembly

C.MADEC - TTC meeting Clean room tools –Coupler to cavity assembly Elevator table + rail Misalignment of coupler axis / post axis –Quad table post CEA design –Bellow assembly: Elevator table and rail

C.MADEC - TTC meeting Clean room tool Standard tools (particle counters, nitrogen gun) Customized tools : –Washing and drying (~ ISO4) machine (WM) –Washing racks 2 cavities and 1 cold coupler box, ½ string tools : posts and ancillaries, Qp box) –Lifting cart : cavity and quad handling in ISO4 –Lifting table : get in the WM –Transfer table : get out of the WM

C.MADEC - TTC meeting Vacuum components Criteria : –Particle free pumps –Slow pumping –Slow venting –Leak detection –Gas analysis Provided by DESY or CEA Tested on PXFEL2 and 3
