Report of Micro-Controle measurements Visit (two MB type 0 Girders manufactured)
29 November 2010
Input from: Germana Riddone, Alexandre Samochkine, Helene Mainaud-Durand, Sylvain Griffet, Monique Dupont

Micro-Controle concept
Main Beam Type 0 Girders with
integrated (glued) V-shaped supports
(SiC) [complete CLIC Two-Beam Module Supporting System (CLIATLSS0006)]
Micro-Controle Supporting System (MB type 0)

Micro-Controle Supporting System (MB type 0)
Station 1
Station 2 Station 3
Girder 1
Girder 2
Measurements layout
V-supports alignment measurements with reference cylinder under loaded (realistic) condition
Dimensional control of the interface plate for the alignment sensors plate
V-supports alignment tolerance (for each girder) ≤ 10 μm (in respect with fabrication drawings tolerances)

Micro-Controle Girders
Risk assessment details for handling and loading of (ceramic) SiC girders and V-supports: EDMS 1103518 v.1
V-supports can sustain statically 80 kg each V-supports can sustain 200 N of horizontal force
V-supports have a Safety factor of 10 (considering fabrication errors)
× Dynamic loading or shock (over going the elastic limit of SiC) can cause rupture
× Dynamic and Active loading should be avoided on Girders
V-supports
If not..
Device of dynamic absorption should be predicted and installed
Transportation protocol for CLIC girders (ceramic): EDMS 1106041 v.1

Not our Girder !!! but result of mishandling of SiC components
