The main purpose of SPIDER (Source for the Production of Ions of Deuterium Extracted from RF plasma) test facility is the investigation and optimization of a negative ion beam produced by the full size ion source for ITER NBIs (Neutral Beam Injectors). Thermal, transient, non-linear FE (Finite Element) analyses and also electrostatic analysis have been performed as a feasibility study, to assess the calorimeter position and the possibility to measure the beam divergence, to decide for maximum pulse duration, to investigate on beam deflection, to study the effect of radiation and to decide about the necessity of an active cooling system.
