Abstract
  • Operation of the thermonuclear fusion experiment ITERrequires additional heating via injection of neutral beams from accelerated negative ions. In the SPIDER testfacility, under construction in Padova, the production of negative ions will be studied and optimised. This test bed will aim at assessing beam characteristics and verifying the source proper operation.STRIKE (Short-Time Retractable Instrumented Kalorimeter Experiment) is a diagnostic used to characterize the SPIDER beam during short pulse operation (several seconds) to verify if the beam meets the ITER requirement about the maximum allowed beam non-uniformity (below ±10%). During long pulse operations, STRIKE is parked off-beam in the vacuum vessel. The most important measurements performed by STRIKE are beam uniformity, beamlet divergence and stripping losses. The major components of STRIKE are 16 1D-CFC (Carbon-Carbon Fibre Composite) tiles, observed at the rear side by a thermal camera. The CFC is a very anisotropic and fragile material. Several experimental campaigns have been carried out to validate the use of CFC in SPIDER, due to the expectedharsh operating conditions. This contribution gives an overview of some tests under high energy flux, aimed at verifying the thermo-mechanical behaviour of several CFC prototype tiles. The tests were performed in the GLADIS facility at IPP (Max-Plank-Institut für Plasmaphysik), Garching. Dedicated linear and non-linear simulations were carried out to interpret the experiments and a comparison of the experimental data with the simulation results is presented. The results of some morphological and structural studies on the material after exposure to the GLADIS beam are also given and compared with analogous analyses carried out before. This work was set up in collaboration and financial support of F4E. (literal)
