“…GmbH Polaris XMS, refered here as the C 2 TN XMS, set at 90°to beam direction. More details about the HRHE-PIXE system can be found in references Chaves et al [1] and Reis et al [2] In this paper, data from a single irradiation are discussed. The target used was a Yb 2 O 3 thick target having its normal tilted 115°( 180°-65°) relative to the direction of a 3.0 MeV proton beam.…”

Analysis of high-resolution EDS particle X-ray emission spectra is typically more complex than standard Si(Li) detector spectra analysis because of the need to carefully account for contributions from minor and satellite transitions. In this work, a pure Yb 2 O 3 sample was irradiated at the high-resolution high-energy-particle X-ray emission setup of C 2 TN, and simultaneous CdTe and X-ray microcalorimeter spectrometer spectra were collected covering both L and K lines. The Yb 2 O 3 high-resolution spectrum was analysed using the DT2 code that allows to include in the fitting model both diagram lines as well as multi-ionisation satellites, radiative auger emission, energy shifted lines (chemical effects) and any other contributions. In this communication, we present the results of the fit of the high-resolution Yb 2 O 3 spectrum and discuss details and problems related to the transitions energy, intensity and line width data.

“…In this work, we present a case study involving the use of the high‐resolution high‐energy (HRHE)‐PIXE system of C 2 TN. Particular emphasis is put in what concerns the capacity of the high‐resolution energy dispersive spectrometer for improving the knowledge about the atomic parameters of Yb 2 O 3 .…”

“…SDs are not very common in the community working with techniques exploiting X-ray detection, but they have started to be used. Since 2010, some applications of high-resolution PIXE have been presented [13][14][15][16]. Very recently, an application to a problem of interest in CH has been presented.…”

“…Since the differences in isotope abundance are typically very small in nature, by convention, the isotope ratio of a sample to a standard is measured in units per thousand (delta notion δ), where the ratio R refers to that of the heavier isotope with respect to the lighter isotope; the most frequently measured isotopes are 13 C/ 12 C (carbon), 15 N/ 14 N (nitrogen), 34 S/ 32 S (sulfur), 18 O/ 16 O (oxygen) and 2 H/ 1 H (hydrogen). Therefore, the delta notion is: δ(‰) = (Rs/Rstd − 1) × 1000, where Rs is the isotopic ratio of the sample and Rstd is that of the reference standard.…”

Detectors and Cultural Heritage: The INFN-CHNet Experience

et al. 2021

Detectors are a key feature of the contemporary scientific approach to cultural heritage (CH), both for diagnostics and conservation. INFN-CHNet is the network of the Italian National Institute of Nuclear Physics that develops and applies new instrumentation for the study of CH. This process results in both optimized traditional state-of-the-art and highly innovative detection setups for spectrometric techniques. Examples of the former are X-rays, gamma-rays, visible-light and particles spectrometers tailored for CH applications, with optimized performances, reliability, weight, transportability, cost, absorbed power, and complementarity with other techniques. Regarding the latter, examples are ARDESIA, the array of detectors at the DAΦNE-Light facility, the MAXRS detection setup at the Riken-RAL muon beamline and the imaging facilities at the LENA Laboratory. Paths for next-generation instruments have been suggested, as in the case of the X-ray Superconductive Detectors and X-ray Microcalorimeter Spectrometers, allowing astonishing improvement in energy resolution. Many issues in CH can now be addressed thanks to scientific techniques exploiting the existing detectors, while many others are still to be addressed and require the development of new approaches and detectors.

“…In the beginning of the 21st century, Transition Edge Sensor (TES) based X-ray Microcalorimeter Spectrometers (XMS) emerged, leading to works as that of Li on the analysis of airborne particles using a TES high resolution energy dispersive spectrometer (EDS) coupled to a Scanning Electron Microscopy (an XMS-SEM in fact), published in 2009 [12], as well as to the installation of the first XMS based PIXE system at Instituto Tecnológico e Nuclear, in 2008 [13,14] (presently C 2 TN-IST/ULisboa), and more recently to the installation of a second generation XMS-PIXE system at the Universty of Jyväskylä [15].…”
