Abstract In this paper we present the performance of a new SiPM that is sensitive to blue light and features narrow metal-filled trenches placed in area around single-photon avalanche diodes (SPADs) allow an almost complete suppression internal optical crosstalk. particular, show benefits technological upgrade terms electro-optical when compared previous technology which had only partial screening between SPADs. The most relevant effect much higher bias voltage can be applied device before...
Inorganic scintillators are widely used for fast timing applications in high-energy physics (HEP) experiments, time-of-flight positron emission tomography and time tagging of soft hard x-ray photons at advanced light sources. As the best coincidence resolution (CTR) achievable is proportional to square root scintillation decay it worth studying cross-luminescence, example BaF2which has an intrinsic yield about 1400 photons/MeV. However, bands BaF2are located deep-UV 195 nm 220 nm, which sets...
Silicon photomultipliers (SiPMs) are single-photon sensitive solid-state detectors that becoming popular for several applications, thanks to massive performance improvements over the last years. Starting as a replacement photomultiplier tube (PMT), they now used in medical big high-energy physics experiments, nuclear spectroscopy, biology and light detection ranging (LIDAR) applications. Due different requirements terms of efficiency, noise, etc., optimizations have been introduced by...

SiPM-based readouts are becoming the standard for light detection in particle detectors given their superior resolution and ease of use with respect to vacuum tube photo-multipliers. However, contributions noise such as dark rate, cross-talk, after-pulsing (AP) may significantly impact performance. In this work, we present development highly reflective single-phase argon chambers capable displaying yields up 32 photo-electrons per keV, approximately 12 being primary generated by...

Abstract This work reports a 1 mol scale catalytic process to synthesize adipic acid directly from cyclohexane in solvent‐free conditions using air as oxidant. Catalysts based on vanadium phosphorus oxides were prepared, characterized and tested. They showed good activity remarkably high selectivity comparison other already known heterogeneous catalysts. The use of permits the easy separation product reactant mixture, which is very important industrial point view. can be used at for...
Some quantitative aspects of laser-irradiated pure metals, while approaching phase explosion, are still not completely understood. Here, we develop a model that describes the main quantities regulating liquid-vapor explosive transition and expulsion liquid nanodroplets that, by solidifying, give rise to nanoparticle formation. The combines both thermodynamics description change Monte Carlo simulation randomly generated critical vapor bubbles. calculation is performed on set seven metals (Al,...
Abstract A large number of particle detectors employ liquid argon as their target material owing to its high scintillation yield and ability drift ionization charge over distances. Scintillation light from is peaked at 128 nm a wavelength shifter required for efficient detection. In this work, we directly compare the achieved in two identical chambers, one which equipped with polyethylene naphthalate (PEN) other tetraphenyl butadiene (TPB) shifter. Both chambers are lined enhanced specular...

Integrated absorber/electrocatalyst schemes are increasingly adopted in the design of photoelectrodes for photoelectrochemical cells because they can take advantage separately optimized components. Such also lead to emergence novel challenges, among which parasitic light absorption and nature absorber/catalyst junction features prominently. By taking versatility pulsed-laser deposition technique, we fabricated a porous iron(III) oxide nanoparticle-assembled coating that is both transparent...
