This work describes a tabletop (50 cm × 25 cm) full field X-ray pinhole camera (FF-XPC) presenting high energy- and spatial-resolution. The FF-XPC consists of conventional charge-coupled device (CCD) detector coupled, in coaxial geometry, to collimator small diameter. fluorescence (XRF) is induced on the samples with an external low-power tube. use CCD as energy dispersive was obtained by adopting multi-image acquisition single photon counting developing processing algorithm be applied...
The LABEC laboratory, the INFN ion beam laboratory of nuclear techniques for environment and cultural heritage, located in Scientific Technological Campus University Florence Sesto Fiorentino, started its operational activities 2004, after decided 2001 to provide our applied physics group with a large dedicated applications accelerator-related analytical techniques, based on new 3 MV Tandetron accelerator. accelerator greatly improved performance existing Ion Beam Analysis (IBA) (for which...
Detectors are a key feature of the contemporary scientific approach to cultural heritage (CH), both for diagnostics and conservation. INFN-CHNet is network Italian National Institute Nuclear Physics that develops applies new instrumentation study CH. This process results in optimized traditional state-of-the-art highly innovative detection setups spectrometric techniques. Examples former X-rays, gamma-rays, visible-light particles spectrometers tailored CH applications, with performances,...
We study the role of defects in ``single-chain magnet'' CoPhOMe by inserting a controlled number diamagnetic impurities. The samples are analyzed with unprecedented accuracy particle induced x-ray emission technique, and ac dc magnetic measurements. In an external applied field system shows unexpected behavior, giving rise to double peak susceptibility. static thermodynamic properties randomly diluted Ising chain alternating $g$ values then exactly obtained via transfer matrix approach....
Silicon-vacancy (SiV) centers in diamond are gaining an increased interest for application, such as quantum technologies and sensing. Due to the strong luminescence concentrated its sharp zero-phonon line at room temperature, SiV being investigated single-photon sources communication, also temperature probes Here, we discussed strategies fabrication of based on Si-ion implantation followed by thermal activation. color high-quality single crystals have best optical properties, but...
At present, macro X-ray fluorescence (MA-XRF) is one of the most essential analytical methods exploited by heritage science. By providing spatial distribution elemental maps, not only does it allow for material characterisation but also to understand, or at least have a likely idea of, production techniques an analysed object. INFN-CHNet, Cultural Heritage Network Italian National Institute Nuclear Physics, designed and developed MA-XRF scanner aiming be lightweight, easy transport piece...
We demonstrate the feasibility of fabricating light-waveguiding microstructures in bulk single-crystal diamond by means direct ion implantation with a scanning microbeam, resulting modulation refractive index ion-beam damaged crystal. Direct evidence waveguiding through such buried microchannels is obtained phase-shift micro-interferometric method allowing study multimodal structure propagating electromagnetic field. The possibility defining optical and photonic structures writing opens...
Single-photon sources are a fundamental element for developing quantum technologies, and based on colour centres in diamonds among the most promising candidates. The well-known nitrogen vacancy characterized by several limitations, thus few other defects have recently been considered. In present work, we characterize, detail, native efficient single emitting near infra-red (λ = 740–780 nm) both standard IIa single-crystal electronic-grade polycrystalline commercial chemical vapour deposited...
We performed high-temperature luminescence studies of silicon-vacancy color centers obtained by ion implantation in single crystal diamond. observed reduction the integrated fluorescence upon increasing temperature, ascribable to a transition channel with an activation energy 180 meV that populates shelving state. Nonetheless, signal decreased only 50% and 75% respect room temperature at 500 K 700 K, respectively. In addition, center is found highly photostable temperatures exceeding 800 K....
The X‐Ray Fluorescence (XRF) scanning spectrometer developed in the framework of Cultural Heritage Network ‐ National Institute Nuclear Physics, is specifically customised for cultural heritage applications, designed with a focus on having lightweight scanner (weighing approximately 10 kg), easy to handle and thus easily transportable two medium‐sized boxes. research presented here deals study set choir books preserved Abbey San Giorgio Maggiore homonymous island Venice. Produced itself from...
