MONNET, Tandem accelerator based fast neutron source (EUFRAT)


Publication date
02 February 2022 in Geel, Belgium
Deadline model


MONNET is a high-intensity quasi mono-energetic fast neutron source, driven by a vertical 3.5 MV Tandem accelerator producing either continuous or pulsed beams of protons, deuterons or helium ions. Quasi mono-energetic neutrons are generated in the energy region 0 - 24 MeV by using lithium, deuterium or tritium targets. MONNET may also be used as a photon source or for studies requiring proton, deuteron or alpha beams without the emphasis on neutron production, provided that there is added value for the JRC to do so.

Definition and conditions of access

Access to the research infrastructure is granted on the basis of Access Units. For MONNET, the Access Unit corresponds to a 'Measurement week' made available for the experimental activities. MONNET operates on a 24h/7 days per week basis. An Access Unit is about 120 hours of beam time and includes the time to build up and to dismantle the experimental set-up (if needed) and can be used partially. Depending on the proposed experiment users can use their own equipment, JRC in-house equipment or a combination of both. This has to be indicated in the proposal and should be coordinated already a few weeks before the scheduled beam time. Preferentially, the users must collaborate closely with an in-house staff scientist (a local scientific contact) who is familiar with the facility and the in-house equipment.

All users will be requested to complete and deliver safety and security-related documents to get access to the nuclear facilities at MONNET. Approval of access is subject to the rules of the European Commission, the Joint Research Centre and the Belgian authorities. Submission of documents should therefore be started in time to allow completion of the approval procedure well before the start of the experiment.

  • Estimated costs excluding consumables and other expenses:
    • Research infrastructure operated by JRC staff: 19,962 € / Measurement week
    • Research infrastructure operated by users: Not possible

Allocation of intellectual property rights:

Intellectual property rights are allocated according to Paragraph III of Annex 1: Intellectual Property Rights.
