Overview

Maria Neutron Laboratory (MNL) utilizes thermal neutrons produced by the MARIA research reactor. Their wavelengths are comparable to interatomic distances in solids, making neutrons a unique tool for investigating the structure and properties of materials. Neutron techniques enable studies of atomic structure, magnetic properties, residual stresses, and processes occurring under real operating conditions.

One of the key features of neutrons is their intrinsic magnetic moment. As a result, neutrons interact not only with atomic nuclei but also with the magnetic ordering of matter. This makes it possible to investigate the arrangement and orientation of magnetic moments within materials and to observe phenomena that are inaccessible to many other experimental techniques. Consequently, neutron methods provide simultaneous insight into both the atomic and magnetic structure of a material.

The experimental hall adjacent to the reactor is equipped with comprehensive technical infrastructure, including technical gas systems, vacuum facilities, cryogenic cooling systems, and supplies of both gaseous and liquid helium. This infrastructure provides full support for advanced neutron experiments and ensures reliable operation of scientific instrumentation.

MNL also operates a helium recovery system that captures, purifies, stores, and reuses helium employed in research activities. This reduces the consumption of fresh helium, minimizes losses of this valuable non-renewable resource, and supports a more sustainable approach to scientific research.
