Analysis of the diagnostic potential of a wire calorimeter for characterization of particle beams

To optimise the particle beam for the nuclear fusion experiment ITER it is necessary to measure the beam parameters with high spacial resolution. This can be done with a diagnostic calorimeter composed by an arrangement of wires made of suitable material. The wires heat up because of the deposition of power due to the particle beam and reach a temperature high enough to irradiate the thermal power received. The present thesis proposes the design of an experiment to calibrate a wire prototype, using ohmic heating to heat the wire observed with a visible camera. A numerical computation is also performed to simulate the results of the ELISE particle beam, operating at Garching bei München IPP.
