TC Final DesignTC Final Design• A PLASTIC SUPPORT STRUCTURE ARRANGES THESCINTILLATOR BARS AS REQUESTED

• THE BARS ARE GLUED ONTOTHE SUPPORT

• INTERFACE ELEMENTS ARE GLUED ONTO THE BARS AND SUPPORT THEFIBRES

• FIBRES ARE GLUED AS WELL

• TEMPORARY ALUMINIUM BEAMS ARE USED TO HANDLE THE DETECTOR DURING INSTALLATION

• PTFE SLIDERS WILL ENSUREA SMOOTH MOTION ALONG THE RAILS
