“…These hardware components are aligned with sub mm precision to the isocenter, that is, the geometric intersection of the neutron beam and the symmetry axis of the gamma detector’s collimator. This facilitates handling data from all modalities in a unified coordinate framework, directly correlating the motor positions, concentrations, and visual information without a registration process [ 40 ]. The sample positioning is based on either real-time visual feedback from the neutron imaging camera or employing a laser beam pointing along the centerline of the neutron beam ( Figure 1 b).…”

Non-destructive characterization of decorated porcelain artifacts requires the joint use of surface-analytical methods for the decorative surface pattern and methods of high penetration depth for bulk-representative chemical composition. In this research, we used position-sensitive X-ray Fluorescence Spectrometry (XRF) and Prompt-gamma activation analysis (PGAA) for these purposes, assisted by 3D structured-light optical scanning and dual-energy X-ray radiography. The proper combination of the near-surface and bulk element composition data can shed light on raw material use and manufacturing technology of ceramics.

“…When the compositions of irregularly-shaped 17 and/or non-homogeneous solid samples 18 are to be determined, in combination with neutron imaging, 19 the correction formulae for regularly-shaped homogeneous samples are no longer applicable. These challenges could be addressed only by employing Monte Carlo computer simulations.…”

The analysis workflow of Prompt gamma activation analysis (PGAA) at the Budapest Neutron Centre’s PGAA and NIPS-NORMA facilities, at the MLZ FRM II PGAA station, and other centers worldwide relied on the use of the Hypermet-PC gamma spectrometry software and the ProSpeRo concentration calculation Excel macro. The sustained interest of our user community amid the reduced availability of multiple large-scale neutron sources worldwide called for more efficient utilization of the operational PGAA facilities. The present paper addresses both measurement and data evaluation bottlenecks of the analysis procedure to achieve higher productivity and superior spectroscopic performance.
