Micro-Controle Supporting System (MB type 0) Micro-Controle concept Main Beam Type 0 Girders with integrated (glued) V-shaped supports (Si. C) [complete CLIC Two-Beam Module Supporting System (CLIATLSS 0006)] 29 November 2010 Nick Gazis, CERN-BE/RF & NTU-Athens 2

Micro-Controle Supporting System (MB type 0) Station 3 Station 2 Station 1 Girder 2 Girder 1 Dimensional control of the interface plate for the alignment sensors plate Measurements layout V-supports alignment tolerance (for each girder) ≤ 10 μm (in respect with fabrication drawings tolerances) V-supports alignment measurements with reference cylinder under loaded (realistic) condition 29 November 2010 Nick Gazis, CERN-BE/RF & NTU-Athens 3

Micro-Controle Girders üV-supports can sustain statically 80 kg each ü V-supports can sustain 200 N of horizontal force üV-supports have a Safety factor of 10 (considering fabrication errors) ×Dynamic loading or shock (over going the elastic limit of Si. C) can cause rupture ×Dynamic and Active loading should be avoided on §Girders §V-supports If not. . ØDevice of dynamic absorption should be predicted and installed Risk assessment details for handling and loading of (ceramic) Si. C girders and V-supports: EDMS 1103518 v. 1 Transportation protocol for CLIC girders (ceramic): EDMS 1106041 v. 1 29 November 2010 Nick Gazis, CERN-BE/RF & NTU-Athens 4

Micro-Controle Girders üV-supports can sustain statically 80 kg each Not our 200 Girder !!! ü V-supports can sustain N of horizontal force üV-supports have aof. Safety factor of 10 of (considering fabrication but result mishandling Si. C components errors) ×Dynamic loading or shock (over going the elastic limit of Si. C) can cause rupture ×Dynamic and Active loading should be avoided on §Girders §V-supports If not. . ØDevice of dynamic absorption should be predicted and installed Risk assessment details for handling and loading of (ceramic) Si.
