The APDL script developed was used to predict the thermalmechanical behavior of the electron beam diagnostic device, which to be mounted on the beam line of a nuclear research facility (the Extreme Light Infrastructure – Nuclear Physics (ELI-NP)). In the first part, we introduce a numerical methodology, based on the ANSYS Parametric Design Language (APDL), to investigate the thermal effects resulting from the interaction of an electron bunched beam hitting a general material surface.
the energy and therefore power applied) and materials are different, but by means of the code we present here, it becomes possible to control the temperature distribution of the mechanical part treated and to consequently properly evaluate the stress induced. įor any one of the previous examples, electron beams (i.e. Another important field of application is the heat treatment (cure) of metals for aircraft, automobiles and recreational equipment, which uses this technology to reduce the time and costs of the process. Among these, for example, are the deposition of chemicals, the irradiation of materials for several purposes (food and medicine included), and the most advanced analytical techniques for the internal structure of materials (tomography). In addition to the current most common applications of the electron beam already mentioned, there are more advanced processes that aim to produce “greener” parts, cheaper and faster than more traditional techniques. The methodology proposed here could be extremely useful in the industrial field, with increasingly varied areas of application emerging in the future. brittleness, and reduction of mechanical strength). Just to give an example, in electron beam welding processes, the evaluation of the heat affected zone (HAZ) is extremely important to finely tune the beam parameters regarding material type and geometry, to minimize the degradation of mechanical material performance in that zone (e.g. For all the above-mentioned branches, the control of the beam parameters and their related interaction with target materials are crucial for the effective and efficient functioning of equipment. It is implemented in a wide spectrum of industrial applications in different fields, such as welding, biological sterilization, microscopy, machining, additive manufacturing, physical vapor deposition, as well as in research facilities for nuclear physics experiments. The most diffuse particle beam in modern industry is the electron beam.
