Conclusions § Assembly: the most critical point is how are we going to assemble it is not possible! § Camera system needs to be redesigned because it clashes. § Gas dump system seems to work well! § Gas injection: a lot of work needs to be done to fit it here especially if we need to move it closer to the IP. § Spacers positions: to be modified for better fit. logo area Giannis Papazoglou, BGC - Gas injection Integration 8
