The Micro-Characterization Laboratory (MCL) is dedicated to the experimental investigation of materials performance in terms of microstructure and micromechanics. The lab provides insight into the complex coupling between microstructure, its defects and the mechanical behaviour of small volumes of metals, ceramic materials, polymers and composites of interest for the safe operation of nuclear installations and for non-power nuclear applications. MCL also offers the possibility of producing nanoparticles by spark ablation method.

Priority topics of MCL
- Micro-characterization of materials of nuclear interest.
- High temperature nanoindentation of metals, alloys and composites.
- Development of new micro-mechanical testing methodologies
- Support to the development of predictive mechanism-based multiscale models of material behaviour.
- Effects of material degradation sources in nuclear environments (irradiation, high temperature, corrosion)
- Understanding of small scale plasticity
- Physical methods of producing nanoparticles for non-power nuclear applications
Definition and conditions of access
Access to the research infrastructure is granted on the basis of Access Units. For MCL, the Access Unit corresponds to an 'AU' and the definition depends on the type of equipment made available to Users.
High temperature nanoindenter, in-situ micromechanical testing system, nanoparticle generator and support microstructural characterization: The AU is “days”. For high temperature nanoindentation, one temperature in one sample can be tested per day. Typical projects will last one or two weeks. It is recommended to have a back-up of 1 – 2 days per sample to account for unexpected issues with temperature stabilization. JRC staff will do operation of the equipment during normal working hours.
For nanoparticle generator and support microstructural characterization: Users may prepare and/or observe their own specimens assisted by JRC staff. The length of such preparations and/or observations depends on each request. JRC staff can provide support to estimate the duration of proposals.
- Estimated total number of Access Unit allocated to the call:
- High temperature nanoindenter and in-situ micromechanical testing system: 20 AU (AU = days)
- Sample preparation equipment and support microstructural characterization: 12 AU (AU = hours)
- Average number of Access Unit per Project:
- High temperature nanoindenter and in-situ micromechanical testing system: 5 AU (AU = days)
- Sample preparation equipment and support microstructural characterization: 3 AU (AU = hours)
- Estimated costs excluding consumables and expenses:
- Research infrastructure operated by JRC staff: 0€ / Day
- Research infrastructure operated by users: Yes
Please note that specimens need to be prepared by the users, either on site or brought ready from their own laboratory.
Support of users for travel and subsistence
The JRC may provide a financial or in-kind contribution to support Users to cover their costs of travel and subsistence (T&S) related to the User Stay Days, subject to the availability of funds, personnel and other resources to Users from User Institutions located in an EU Member State or country associated to the Euratom Research Programme (only United Kingdom and Ukraine).
A User Stay Day is a day of physical presence of a User at the concerned Research Infrastructure for Access related to the User Access Project. A User Stay Day counts as a registered entry to the JRC site where the Research Infrastructure is located.
- Estimated total number of User Stay Days for short- term stays eligible for T&S allocated to the call: 40
- Estimated total number for long- term stays (months) eligible for T&S allocated to the call: 16
Long term stays are primarily for students and have a duration of at least 1 month. They are typically 3 to 9 months for Karlsruhe, and 1 to 6 months for Petten and Geel.
The Lead Used is welcomed to fill in the User travel and subsistence form and send it to JRC-OPEN-MCL@ec.europa.eu by the closing date of the call. For more information the Lead User may contact the JRC Research Infrastructure at JRC-OPEN-MCL@ec.europa.eu
