Zanini, Marco (2014) Analysis of the diagnostic potential of a wire calorimeter for characterization of particle beams. [Laurea triennale]
Full text disponibile come:
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.
