<title>Abstract</title> Single photon detection is the underpinning technology for quantum communication and sensing applications. At visible near-infrared wavelengths, single-photon-detectors (SPDs) underwent a significant development in past two decades, with commercialization of SPADs superconducting detectors. longer mid-infrared range (4-11µm), given reduced scattering favourable transparent atmospheric windows, there an interest developing earth-satellites-links imaging noisy...
The experimental thermal neutron cross sections of the 20 proteinogenic amino acids have been measured over incident-neutron energy range spanning from 1 meV to 10 keV and data interpreted using multi-phonon expansion based on first-principles calculations. scattering section, dominated by incoherent inelastic contribution hydrogen atoms, can be rationalised in terms average contributions different functional groups, thus neglecting their correlation. These results used for modelling total...
In this work, we discuss an improved detection procedure for the photon-sensitive yttrium-aluminum-perovskite detectors installed on VESUVIO spectrometer at ISIS pulsed neutron and muon source. By decreasing low-level energy threshold of detected photons, observe increased count rate up to a factor ∼3, decrease relative error bars noise ∼40% 35%, respectively, deep inelastic scattering measurements. addition, demonstrate how reported optimization may increase accuracy in line shape analysis...
New evidence of the increased count rate in deep inelastic neutron scattering spectra is provided. Experiments were performed using photon-sensitive yttrium-aluminum-perovskite detectors, installed on VESUVIO spectrometer at ISIS pulsed and muon source. At present, these detectors work with a low-level discrimination threshold measuring photons energy greater than 600 keV order to avoid background from boron beam stop, other environmental sources. We discuss advantage reducing level so as...
The VESUVIO spectrometer at the ISIS pulsed neutron and muon source is a unique instrument which makes use of eV neutrons inverted geometry, allowing deep inelastic scattering experiments with high values energy wavevector transfers. detection techniques on forward-scattering detector banks based (n,γ) conversion, therefore are indirectly detected signals produced by scattered neutrons, accordingly photons, recorded using gamma scintillators. γ-sensitive detectors make γ-background one main...
We present an experimental investigation of the hydrogen nuclear momentum distribution in biphenyl using deep inelastic neutron scattering. Our results suggest that local potential affecting is both harmonic and isotropic within uncertainties. This feature interpreted as a consequence central limit theorem, whereby three-dimensional expected to become purely Gaussian function number independent vibrational modes system increases. also performed ab initio phonon calculations on other...

Abstract Background Boron‐containing compounds, such as 4‐borono‐phenylalanine (BPA) are used drugs for cancer treatment in the framework of Boron Neutron Capture Therapy (BNCT). irradiation boron‐rich compounds delivered to cells triggers nuclear reactions that destroy cells. Purpose We provide a modeling thermal neutron cross section BPA, drug (BNCT), quantify competing contributions boron absorption against hydrogen scattering, optimizing BNCT by minimizing latter. Methods perform...
The composite and nanocomposite are often used in several fields for different applications: aerospace, automotive, biomedical electronics. In particular, these last years aerospace sciences, the amount of composites loaded with nanostructures is increased. One relevant application use nanocarbon based as a coating to protect electrical circuits from possible electromagnetic waves interferences, which could damage performance devices. There many advantages polymeric matrix carbon...
The present and future developments of time-resolved prompt-gamma activation analysis (T-PGAA) at pulsed neutron sources is discussed in the framework successful history neutron-activation techniques.
