The Czech Technical University in Prague is currently building a new neutron imaging instrument named TRIXIE at the research reactor LVR-15. The LVR-15 is a 10 MW reactor located in Rez, near Prague, in the Czech Republic. The TRIXIE project started in the spring of 2022, establishing a conceptual design of the major components. This is the result of a collaboration between Czech Technical University in Prague, Helmholtz-Zentrum Berlin and Heinz Maier-Leibnitz Zentrum (FRM II). The TRIXIE instrument is intended for thermal neutron radiography and tomography techniques. This instrument comprises components such as fast neutron and gamma filters, a beam collimator with an aperture for thermal neutrons and primary and secondary shutters. The experimental area is a large shielding structure with a detection system, sample positioning tables and other equipment placed approximately 5 m away from the source. The TRIXIE instrument is expected to be completed by the beginning of 2025, and it will provide access to national and international user communities in various research disciplines. This should help to fill the gap between high users’ requests and insufficient capabilities, which existing neutron imaging instruments provide nowadays in Europe.
