Thermal Analysis of the Linac3 GTS-LHC ECR Ion Source

The Linac3 ion source produces lead beams by the vaporization of solid samples inside internal ovens. The geometry, materials and surface state of the oven elements are critical parameters influencing the temperature distribution in the environment, and thus the performance of the source. A finite element approach is proposed to evaluate the thermal response of the system at increasing heating powers. Comparisons between the simulations results and experimental measurements are given in order to validate the numerical model. Based on the obtained results, improvements to the existing setup are suggested.
