Job Details

Join our R&D program supporting the design, test, and operation of the MYRRHA proton accelerator!

SCK CEN works actively on the design and construction of a new multi-purpose research plant MYRRHA: a versatile and unique research infrastructure. It is the world’s first research reactor driven by a proton linear accelerator (linac). A 100 MeV linac will be constructed first. The beam-commissioning of this accelerator facility is scheduled for 2027. Within the MYRRHA Phase 1, the main objectives are the design, construction, commissioning, operation of the 100 MeV proton linac coupled to a target facility with applications in fundamental research, in the production of medical radioisotopes and in material research for fusion. In a second stage it will be upgraded to 600 MeV and later connected to the MYRRHA reactor. Unlike traditional reactors, cooling the reactor core is not done with water but using a liquid metal mixture of lead and bismuth. This mixture offers the advantage that it does not slow down the fission neutrons. These fast neutrons unlock a variety of applications.

The Accelerator Technologies and Systems (ATS) group is responsible for the design, construction and commissioning of the 100 MeV superconducting linac, in close collaboration with several national and international research institutes and industrial partners. The selected candidate will be a member of the ATS group and will be based at SCK CEN Mol.

As Cryogenics Engineer for the 100 MeV superconducting linac, you will be co-responsible for the cryogenic equipment (cryomodule and valve boxes) ensuring its global engineering coherence within the overall system. You will interface with researchers and technicians, in the realization and operation of experimental facilities related to the cryogenic equipment and their components.

The Cryogenics Engineer will have the following responsibilities within ATS:

  • support all engineering activities and system integrations of the cryogenic equipment, such as design, engineering, prototyping, industrialisation, installation, operation, maintenance, improvement;
  • perform/support the design consolidation of the cryogenic equipment;
  • prepare the technical documentation for the public procurement of the cryogenic equipment;
  • perform the technical follow up of the public procurement contracts, including manufacturing and acceptance testing, of the cryogenic equipment;
  • perform the technical follow up of the cryomodule assembly and testing;
  • ensure the full documentation of the cryogenic equipment during its entire life cycle. This includes documentation during the design phase (requirements, technical specifications, acceptance criteria), the procurement phase (suppliers selection, contract follow-up), the production phase (manufacturing, assembly, tests), the installation phase (integration, commissioning), and the exploitation phase;
  • once applicable, participate in the commissioning and operation of the overall cryogenic system.

To join this frontier, you’ll need

  • Master’s degree in Physics, Engineering or related field; a PhD is appreciated;
  • broad understanding of low temperature physics, knowledge of large scale cryogenic systems and techniques;
  • formal background knowledge of cryogenic systems and infrastructures intended for experimental fundamental research (e.g., condensed matter, high energy physics);
  • experience in design and hardware development of cryogenic systems and the integration of cryogenic subsystems;
  • a basic understanding of particle accelerators is an asset;
  • professional background in an R&D environment (in industry or in research);
  • a positive “can do” attitude, able to show commitment, and to inspire others;
  • pragmatic, dynamic, resistant to stress, rigorous;
  • good interpersonal skills: communication, coordination, and reporting;
  • excellent oral and written skills in English.
