Proton Target Research


In order to replace the ageing BR2 research reactor, SCK•CEN is developing MYRRHA (Multi-purpose hybrid research reactor for high-tech application). This reactor is conceived as an accelerator driven system, using a high-intensity proton beam from a linear accelerator. In the phased approach implementation of the project, a section of the MYRRHA accelerator delivering a 100-MeV proton beam will first be constructed and commissioned. Besides proving the reliability requirements of MYRRHA, the main application of this first phase accelerator is the planned Proton Target Facility (PTF) where the 100-MeV protons will be used for the production of radioisotopes primarily for medical purposes.

One of the envisaged methods for production of radioisotopes at the PTF facility is the Isotope Separation OnLine (ISOL) method. Producing medical isotopes through this method requires the design of an isotope collection station where the radioactive ion beam from the ISOL system can be implanted onto/into a collection medium. This study will be focused on defining several aspects of the collection station design for few isotopes currently of great scientific and medical interest.


The goal of this work is to design a collection station at PTF that is capable of delivering the required doses of selected isotopes to enable clinical trials.


  • Literature study on the ISOL method and the production of medical isotopes via this method

  • Definition of collection strategy for each selected isotope: Collection of isotopes of interest or its parents, optimum collection time.

  • Introduction to particle transport calculations with the Monte Carlo tool FLUKA

  • FLUKA simulations to determine stopping range of beams of each of the selected isotopes in its collection medium and define the required thickness of this medium (accounting for impurities in the beam).

  • FLUKA simulations to assess the activation of the collection medium (Short-term) and other materials at the collection station (Long-term).

  • FLUKA simulations to define the required shielding of the collection medium for its transportation.

  • FLUKA simulations to compute the required shielding of the collection station during operation.
