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
