The negative ion source SPIDER produces a beam power that has to be absorbed by a beam dump component made of stacked hypervapotrons. The manufacturing process produced dimension errors that have given rise to a possible shine-through issue. Finite volume models were developed to carry out transient thermal analyses aiming at validating the design of a system made of copper screens to shield the heat loads passing through the beam dump. The evaluation of the best solution was conducted by looking both at the thermal performances and the technical feasibility. The results show the capability of the system to safely withstand the heat power up to one hour.
