Figure 1: Schematic diagram of the experimental setup.

A pulsed neutron beam travels towards the neutron counting detector installed at ~8.2 m from the source. Both position (~55 μm) and time (0.1–1 μs) are measured by the detector for each registered neutron. A furnace with a BaBrCl:Eu charge is installed a few centimeters from the detector. A set of images, each corresponding to a particular neutron energy, is acquired in each experiment, spanning neutron energies from epithermal range (1–100 eV) to cold neutrons of meV energies. 262,144 spectra are acquired simultaneously (within each of the 512 × 512 pixels of 55 × 55 μm² area).
