Miscellaneous14.1 Advances in the IGNITOR ProgrammeThe detailed design of all the components of the machine load assembly has beenCompletion of completed. This is indeed a remarkable accomplishment in itself, as IGNITOR continuesthe IGNITOR to be the only experiment capable of reaching ignition conditions on the basis of thepresent knowledge of plasma physics and available technology. The operation scenariosdesignconsidered are for maximum plasma performance at 13 T and 11 MA, and reducedscenarios at 9 T, 7 MA (limiter configuration) and 9 T, 6 MA (double null configuration). Inthe framework of the Ansaldo industrial contribution to the engineering design, the 3D nonlinear structuralanalysis of the central post, central solenoid (CS) and poloidal field coil (PFC) systems, plasma chamberand first-wall systems, and of the surrounding mechanical structures (C-clamps) has confirmed that theycan withstand both normal and off-normal operating loads, as well as plasma chamber baking operations,with proper safety margins. Both 3D and 2D drawings (fig. 14.1) of each individual component wereproduced with the use of the Dassault Systems CATIA-V software, including the electro-fluidic and fluidiclines which supply electrical currents and helium cooling gas to the coils [14.1].Fig. 14.1 - IGNITOR load assembly2007 Progress Report184[14.1] A.
