The LHCb experiment at CERN has been upgraded for the Run 3 operation of Large Hadron Collider (LHC). A new concept tracking detector based on Scintillating Fibres (SciFi) read out with multichannel silicon photomultipliers (SiPMs) was installed during its upgrade. One main challenges SciFi tracker will face 4 LHC is higher radiation environment due to fast neutrons, where SiPMs are located. To cope increase in radiation, cryogenic cooling liquid nitrogen being investigated as a possible...
Although inorganic scintillators are widely used in the design of electromagnetic calorimeters for high-energy physics and astrophysics, their crystalline nature and, hence, lattice orientation generally neglected detector design. However, general, features field experienced by particles impinging on a crystal at small angle with respect to axis affect interaction mechanisms. In particular, case electrons/photons (10 GeV) or higher high- Z an ≲ 1 mrad, so-called strong regime is attained:...
We observed a substantial increase of the scintillation light output lead tungstate (PbWO$_4$) at small incidence angle with respect to two main lattice axes. This reflects acceleration electromagnetic shower development that occurs in crystalline Strong Field. measured generated by $120$-$\mathrm{GeV}$ electrons and $10$-$100$-$\mathrm{GeV}$ $\gamma$ rays on thick samples. result deepens knowledge mechanisms crystal scintillators could pave way innovative accelerator- space-borne calorimeters.
Abstract An intense positron sources is a demanding element in the design of future lepton colliders. A crystal-based hybrid source could be an alternative to more conventional scheme based on electron conversion into thick amorphous target. The conceptual idea have two separate objects, photon radiator and photon-to-positron converter In such beam crosses thin axially oriented crystal with emission channeling radiation, characterized by considerably larger amount photons if compared...
The genus Leptoconops Skuse (Diptera: Ceratopogonidae) are blood-sucking midges known to pester humans and domestic animals. In certain Mediterranean areas, occur in large numbers during summer limit the use of recreational also raising serious health social concerns. Despite such impact, diversity distribution Maremma Regional Park (Tuscany Region, Italy), a heavily infested area, is not well known, neither molecular nor detailed morphological studies exist. We sampled adult midge females...
In 2018, a test run with muons in the North Area at CERN was performed, running parasitically downstream of COMPASS spectrometer. The aim to investigate elastic interactions on atomic electrons, an experimental configuration similar one proposed by project MUonE, which plans perform very precise measurement differential cross-section interactions. taking data 190 GeV pion beam, stopped tungsten beam dump: from these pions decays passed through setup including graphite target followed 10...
Calorimeters based on oriented crystals provide unparalleled compactness and resolution in measuring the energy of electromagnetic particles. Recent experiments performed at CERN DESY beamlines by AXIAL/ELIOT demonstrated a significant reduction radiation length inside tungsten PbWO$_4$, latter being scintillator used for CMS ECAL, observed when incident particle trajectory is aligned with lattice axis within $\sim 1^{\circ}$. This remarkable effect, over wide range from few GeV to 1 TeV or...

Chemically defined offer several advantages, as they are free animal-derived components guarantee high purity consistency their composition. Microorganisms genus Leishmania represent promising cellular platform recombinant proteins, but maintenance requires supplements animal origin, such hemin fetal bovine serum. In...
A novel concept to enhance the photo-detection efficiency (PDE) of silicon photomultipliers (SiPMs) has been applied and remarkable positive results can be reported.

Nowadays, it is well known that the electromagnetic interaction between high-energy particles and matter experiences substantial modifications when latter consists of a crystalline medium its lattice axes are almost parallel to input beam direction. In particular, strong boost cross section bremsstrahlung by electrons positrons in high-density oriented crystals has been observed $10$-to-$100~\mathrm{GeV}$ regime. This effect proves particularly appealing comes inorganic scintillators, given...

Abstract Antiproton annihilations on matter nuclei are usually detected by tracking the charged pions emitted in process. A detector made of plastic scintillating bars have been built and used ASACUSA experiment for last 10 years. Ageing, movements transports caused stress internal mechanical structure impacted mostly optical readout system which was eventually upgraded: so far multi-anode photo-multiplier tubes (PMTs) replaced silicon photomultipliers (SiPM) front-end electronics had to be...
Experiments with antiprotons often require the tracking of charged particles emerging from annihilation process. The Atomic Spectroscopy And Collisions Using Slow Antiprotons (ASACUSA) collaboration at CERN Antiproton Decelerator (AD) used several panels scintillating bars placed around interaction region to detect passage pions and determine vertex position time. were composed by extruded light was collected using WaveLength Shifting (WLS) fibers multi-anode PhotoMultiplier Tubes (PMTs)....

For more than half a century, expensive and bulky modules (e.g. the standard NIM, Nuclear Instrumentation Modules) electronic boards have been used in nuclear physics laboratory courses, order to filter, shape digitize analog signals coming from particle detectors. Recently it has become technically possible miniaturize these circuits within ASICs, but their high cost specificity make them unsuitable didactic general-purpose context. In this contribution we present an innovative system for...
It is well known that the lattice structure of a scintillating crystal can influence development electromagnetic processes inside it. For electron and photon beams aligned with symmetry axis crystal, if Strong Field condition satisfied, reduction radiation length (X$_0$) expected. However, these effects have been experimentally observed only in last few years, samples limited number, composition length. The lack experimental data for phenomena makes it harder to properly account them design...
