“…The artifacts were analyzed in the frame of the collaboration between the Department of ancient and modern civilizations of Messina University, the Lipari Museum of Messina, the private Faranda's collection of Catania, the YOuth in COnservation of CUltural Heritage, YOCOCU in Rome and the MIRAS Social Organization in Support of Studying of Cultural Heritage in Azerbaijan from the Italian partner. Many of such analyzed samples were discussed in previous published articles [21][22][23][24].…”

“…Figure 9 reports the LAMQS spectra relative to the ablated masses from a bronze coin in high ultra-vacuum conditions relative a coin excavation of the VI-VII A.D. from Southern Italy (Catania, Sicily). The mass spectrum acquired in the range 100-300 amu shows many chemical compounds of the Fe, Cu, Sn and Pb, typical of the bronze and of the surface patina layer, which is rich in chlorides, oxides and sulphate compounds [24]. The analysis was performed using a Nd:YAG laser operating at 1064 nm wavelength, 3 ns pulse duration and 30 mJ pulse energy, focused on the coin's 2020 JINST 15 C04050 surface, producing a spot of about 500 microns in diameter and used at 10 Hz repetition rate during the MQS spectrum acquisition.…”

An overview of physical investigations of cultural heritage samples using ion and laser beams performed in the frame of the international collaboration between the University of Messina (Italy) and the Nuclear Physics Institute-ASCR (Czech Republic) is presented. Solid samples are analysed in high vacuum using particle induced X-ray emission, Rutherford backscattering spectrometry, elastic recoil detection analysis, prompt γ activation analysis, nuclear reaction analysis, laser ablation, mass spectrometry, scanning electron microscopy, and many more. The elemental composition of the sample, the trace elements, the depth profiles, the morphology and the comparison between samples and references are reported. Both electron and ion microbeams are employed to have details of the spatial distribution maps of elements of interest.

“…Finally we should also mention our mass quarupole spectrometer (MQS), a Prisma-Pfeifer from Mod.100-300, permitting the atom mass recognition from 1 up to 300 amu using an electron multiplier (SEM) as detector with a sensitivity lower than 1 ppm (part per million), as presented in our previous papers [11]. Faraday cup, ion collectors with electron suppression grid, fast storage oscilloscope, semiconductor detectors, plastic scintillators, electron multipliers, MCP, gafchromix and track detectors are employed for the particle detection.…”

Abstract. The pulsed laser-generated plasma in vacuum and at low and high intensities can be characterized using different physical diagnostics. The charge particles emission can be characterized using magnetic, electric and magnet-electrical spectrometers. Such on-line techniques are often based on time-of-flight (TOF) measurements. A 90° electric deflection system is employed as ion energy analyzer (IEA) acting as a filter of the mass-to-charge ratio of emitted ions towards a secondary electron multiplier. It determines the ion energy and charge state distributions. The measure of the ion and electron currents as a function of the mass-to-charge ratio can be also determined by a magnetic deflector spectrometer, using a magnetic field of the order of 0.35 T, orthogonal to the ion incident direction, and an array of little ion collectors (IC) at different angles. A Thomson parabola spectrometer, employing gaf-chromix as detector, permits to be employed for ion mass, energy and charge state recognition. Mass quadrupole spectrometry, based on radiofrequency electric field oscillations, can be employed to characterize the plasma ion emission. Measurements performed on plasma produced by different lasers, irradiation conditions and targets are presented and discussed. Complementary measurements, based on mass and optical spectroscopy, semiconductor detectors, fast CCD camera and Langmuir probes are also employed for the full plasma characterization. Simulation programs, such as SRIM, SREM, and COMSOL are employed for the charge particle recognition.
