Construction and assembly of the neutron radiography and tomography facility ANTARES at FRM II

Neutrons and music: Imaging investigation of ancient wind musical instruments

“…In both neutron and X-ray set-ups signals are detected by a scintillator-CCD camera system with field of view of 220 Â 260 mm and 2160 Â 2560 pixels. For neutrons, 6 LiF:ZnS scintillators (thickness 100 lm) were used while for X-rays green-emitting converter foils (CAWO™ OG 8) were used. The scintillation foil was changed from a neutron and X-ray configurations.…”

“…The 3D structure is reconstructed based on a set of 2D projections, recorded at different angles by rotating the sample around a defined axis [4,6]. When the neutron or X-ray beam is transmitted through a sample, part of the radiation is attenuated by the sample material.…”

Imaging of dynamic magnetic fields with spin-polarized neutron beams

“…In this paper we demonstrate how similar methods can be implemented for studies of dynamic magnetic fields. However, the limited neutron flux available even at the present state-of-the-art neutron imaging facilities [15][16][17][18][19][20] necessarily limits these dynamic studies to either slowly changing magnetic fields (<1 Hz ) or to periodic or cyclical processes where measurements of multiple cycles can be performed, in order to acquire sufficient neutron statistics for adequate imaging. Importantly however, the frequency of the periodic field can be as high as ∼100 kHz, as the timing resolution of present neutron imaging detectors is in a sub-microsecond range [21].…”

Simultaneous and integrated neutron-based techniques for material analysis of a metallic ancient flute

“…8 Present address: ENEA-Cenro Ricerche Frascati, Via E Fermi 45, 00044 Frascati, Rome, Italy. and neutron tomography (NT) [5,6] recognize internal features of the samples. All these techniques have shown their potential in the investigation of complex artifacts of cultural and artistic relevance (see for instance [7][8][9][10][11][12]).…”
