TL;DR
This paper demonstrates the use of time-resolved neutron imaging at the ANTARES beamline to study dynamic processes with high temporal and spatial resolution, enabling detailed analysis of water distribution in a model steam engine.
Contribution
The study showcases the capabilities of time-resolved neutron radiography using a fast detector and TOF technique at ANTARES, enabling dynamic imaging of processes like water flow in engines.

Achieved sub-mm spatial resolution with less than 10 minutes of integration.
Measured neutron spectrum and transmission spectra with high energy resolution.
Abstract
In non-destructive evaluation with X-rays light elements embedded in dense, heavy (or high-Z) matrices show little contrast and their structural details can hardly be revealed. Neutron radiography, on the other hand, provides a solution for those cases, in particular for hydrogenous materials, owing to the large neutron scattering cross section of hydrogen and uncorrelated dependency of neutron cross section on the atomic number. The majority of neutron imaging experiments at the present time is conducted with static objects mainly due to the limited flux intensity of neutron beamline facilities and sometimes due to the limitations of the detectors. However, some applications require the studies of dynamic phenomena and can now be conducted at several high intensity beamlines such as the recently rebuilt ANTARES beam line at the FRM-II reactor. In this paper we demonstrate the…
