Significant progress has been made in the last years in the field of volcanic muography. This technique takes advantage of the large penetrating power of atmospheric muons and allows us to infer information about the internal structure of volcanoes observing the differential absorption of muons passing through the target.
This, in conjunction with other monitoring techniques, can help...

Searches for New Physics effects at the intensity frontier are based on very precise measurements of observables involving rare processes within the Standard Model. Semileptonic decays of $B$ meson are particularly interesting due to persistent hints of Lepton Flavour Universality (LFU) violation seen in $b\to c\tau\nu_\tau$ transitions with a massive $\tau$ lepton in the final state. Compared...

The determination of neutrino mass ordering (NMO) is one of the prime goals of several neutrino experiments. KM3NeT/ORCA and JUNO are two next-generation neutrino oscillation experiments both aiming at addressing this question. ORCA can determine the NMO by probing Earth matter effects on the oscillation of atmospheric neutrinos in the GeV energy range. JUNO, on the other hand, is sensitive to...

Optical systems for RICH detectors have historically taken a variety of designs. Nowadays, technological developments allow more flexibility in the design and construction than allowed in the past, such as lightweight secondary mirrors to be placed in acceptance, widespread use of non-spherical optical surfaces, flexible and fast tools for parametric optimization of the optical systems before...

The Latin American Giant Observatory (LAGO) is a ground based observatory studying solar or high energy astrophysics transient events. LAGO takes advantage of its distributed network of Water Cherenkov Detectors (WCDs) in Latin America as a tool to measure the secondary particle flux reaching the ground. These secondary particles are produced during the interaction of the modulated cosmic rays...

Various ring imaging Cherenkov sub-systems are being proposed in EIC detector for hadron identification with momenta up to 50 GeV/c. It is critical to have a reliable highly pixelated readout sensor working in the high magnetic field environment. Optimization of the photosensor design for high magnetic field tolerance, precision timing resolution, and pixelated readout was performed at Argonne...

Large Area Picosecond Photon Detectors (LAPPDs) are micro-channel plate (MCP) based photosensors featuring hundreds of square centimeters of sensitive area in a single package and capable of providing timing resolution on the order of 30-50 ps for single photon detection. One of the recent LAPPD models (Gen II) gives the opportunity of building finely pixelated 2D readout configurations which,...

Microchannel Plates (MCPs) are used in many applications, including in Cherenkov and scintillation detectors. There are several characteristics that need to be considered when designing MCPs for such applications. The time resolution and gain are two important characteristics that affect the ability to measure a pulse and the time between interactions that can be measured.

Since 2018 an aerogel proximity focusing Ring Imaging Detector (ARICH) efficiently separates hadrons in the forward endcap of the Belle II spectrometer. Cherenkov photons emitted in the double layer aerogel radiator are expanded in the 16 cm space and detected on the photon detector comprising 420 Hybrid avalanche photodiodes and backside readout electronics working in a threshold mode. Each...

The Belle II barrel region is instrumented with the Time of Propagation (TOP) particle identification system comprising sixteen quartz radiator bars arranged around the interaction point. These quartz bars do not overlap, leaving a gap of around 2cm in the azimuthal direction between them and causing a 6% drop in acceptance. An additional 3% of tracks suffer from degraded identification...

Hadron identification in LHCb after the high luminosity LHC upgrade (Run 5) will be extremely challenging. A number of different technologies are under study, including the use of aerogel as a Cherenkov radiator. Novel pinhole drying hydrophobic aerogel radiators have improved transparency compared to the tiles used in the Belle II ARICH. In the framework of the LHCb RICH Upgrade we are...

Cherenkov light is used in a wide variety of neutrino detectors for observing the secondary charged particles produced after neutrino interactions. The SNO+ experiment has reported a discrepancy between data and Monte-Carlo in the isotropy of the Cherenkov light emitted by electrons with energies of a few MeV. SNO+ relies on Geant4, a widely used simulation package, to approximate the...

Gamma-Ray Bursts (GRBs) are of the brightest transients detected, with typical energies in their prompt phase ranging from keV to GeV. Theoretical models predict emissions at higher energies in the early times of the afterglow emission, and recently GRB190114C was the first GRB detected at TeV energies by the MAGIC experiment.
