The provenance of raw lapis lazuli used since the Neolithic Age for the realization of carved artefacts can be pivoting for the reconstruction of ancient trade routes. The role of main provider of this material in ancient times is generally attributed to the Badakhshan quarries (Afghanistan), although other deposits could have been exploited as well since antiquity. The systematic multi-technique analysis of lapis lazuli rocks coming from four known source areas (located in present-day Afghanistan, Tajikistan, Siberia and Chile) has led in the last years to the compilation of a protocol for provenance determination. The protocol is based on differences in the physical–chemical properties measured with non-invasive techniques (Ion Beam Analysis (IBA)), making it suitable also for precious ancient artefacts. In this work, 10 new reference samples from the Mogok quarry (Myanmar), previously subjected to a complete petrographic and mineralogical characterization, have been analysed employing $$\mu$$ μ -PIXE (Proton Induced X-ray Emission) and $$\mu$$ μ -IBIL (Ion Beam Induced Luminescence) techniques. The subdivision of Myanmar samples into three groups, previously suggested, is corroborated by diopside trace elements concentrations. The results also allow to include Myanmar as a new provenance in the analytical protocol, indicating that provenance markers such as presence/absence of wollastonite, altered pyrites and Sr content are still valid to discriminate also the Myanmar lapis lazuli from Chilean or Siberian ones. New weaker markers (Zn content in diopside, Se and Cu contents in pyrite) are proposed for the discrimination of Myanmar from Afghan or Tajik provenances; however, from the analysis it arose the need of investigating new mineral phases with IBA to find strong markers for a definitive discrimination with samples from Southwest Asia.

“…In this case, despite the thickness of 50 µm of the intrinsic diamond, the region where the charges are efficiently collected is limited to a shallow layer by the superficial positioning of the electrodes. Therefore, the CCE of the interdigit diamond detector has a maximum for all those low-energy particles completely stopped near its surface and will start to decrease for more penetrant particles [16,22]. Nevertheless, the IEC shows an improvement in the time response velocity of charge collection also thanks to the very low capacitance.…”

Single crystal diamond detectors are widely employed in laser-induced plasma experiments to retrieve information about particles generated from the interaction. In particular, diamonds are used as Time of Flight (TOF) detectors featured by good sensitivity, high radiation hardness and fast response time. In this work, we provide a detailed characterization of two different types of electrodes configuration retrieving their charge collection efficiency, temporal response, and effective active area. The so obtained information are then used to compute calibrated proton spectra from the signals collected by the two investigated detectors employed in TOF schemes during an experimental campaign performed with the femtosecond FLAME laser (reaching >100 TW power and ∼1019 W/cm2 intensity) interacting with thin foil targets. Despite the different detection characteristics of the two diamond detectors, consistent information about the detected protons were obtained.

“…The Charge Collection Efficiency was estimated by exposing the detector to the 241 Am sample for 300 s. Thus, several events were detected by the diamond detector during the acquisition time. The output signals were processed by a conventional charge-sensitive electronic chain [12,13,20]. They were first integrated by a charge-sensitive preamplifier (ORTEC 142A).…”

Time-Of-Flight (TOF) technique coupled with semiconductor detectors is a powerful instrument to provide real-time characterization of ions accelerated because of laser-matter interactions. Nevertheless, the presence of strong electromagnetic pulses (EMPs) generated during the interactions, can severely hinder its employment. For this reason, the diagnostic system must be designed to have high EMP shielding. Here we present a new advanced prototype of detector, developed at ENEA-Centro Ricerche Frascati (Italy), with a large area (15 mm × 15 mm) polycrystalline diamond sensor having 150 µm thickness. The tailored detector design and testing ensure high sensitivity and, thanks to the fast temporal response, high energy resolution of the reconstructed ion spectrum. The detector was offline calibrated and then successfully tested during an experimental campaign carried out at the PHELIX laser facility (𝐸 𝐿 ∼100 J, 𝜏 𝐿 = 750 fs, 𝐼 𝐿 ∼ (1 − 2.5) × 10 19 W cm -2 ) at GSI (Germany). The high rejection to EMP fields was demonstrated and suitable calibrated spectra of the accelerated protons were obtained.
