Proton Target Research


In order to replace the ageing BR2 research reactor, SCK•CEN is developing the MYRRHA reactor. This fast reactor is conceived as an accelerator driven system, using a high-intensity proton beam from a linear accelerator. Part of the beam from this accelerator will be sent towards several target stations, dedicated to the production of radioactive isotopes for various purposes, such as medical applications, material research or fundamental-physics studies. One of the foreseen target stations will be part of an isotope-separation online (ISOL) installation, for the production and study of exotic radioactive nuclei. The high intensity of the proton beam which is beneficial in producing higher yields also entails the need for development of new high-power targets for this facility. The container that will hold these target materials will have to withstand temperatures up to 2300ºC in a radiation environment. For a good performance of this target it is important that its temperature is as uniform as possible. To test the performance and durability of the target container, a test step-up is being built at SCK•CEN where a target container will be heated by a high current power supply in a high vacuum chamber, temperatures will be measured with a pyrometer.


The main goal of this work is to model the electrical heating of the target container in FEM software (ANSYS) and validate the calculations in an experimental set-up. Once the simulations are experimentally confirmed, suggestions for improvements of the geometry can be checked within ANSYS.
