In order to satisfy both count rate requirements of over 2 Mcps/mm2 and spatial resolution requirements in PCCT, sub-mm pitch silicon photomultiplier array using silicon on insulator technology (SOI-SiPM) was fabricated and evaluated...

Detectors at future accelerators will require operation at rates up to three orders of magnitude higher than 15 kHz/cm$^2$, the hit rates expected in the current upgrades forward muon detectors of LHC experiments. A resistive Micromegas detectors with modified readout system can achieve rate capability up to few MHz/cm$^2$ and low occupancy, thanks to few mm$^2$ readout pads. We present the...

The Compressed Baryonic Matter (CBM) experiment aims at exploring the QCD phase diagram at large baryon densities with heavy ion beams in the beam energy range from 2 A GeV to 11 A GeV at the SIS100 accelerator of FAIR/GSI. For charged particle identification that is required by many observables that are sensitive to the phase structure like collective flow, phase space population of rare...

This work describes a comprehensive study of metal contacts on single crystals of II-VI group semiconductors, Cd1-xZnxTe and Cd1-xMnxTe. Both materials are candidates for numerous detector applications, while the former is more established, the latter has potential advantages. In this work we formed metal contacts on high resistivity Bridgman grown Cd1-xZnxTe and Cd1-xMnxTe crystals by thermal...

Scintillation crystals are widely used in detectors for high energy physics and medical physics. For positron emission tomography (PET), a major approach to improve the signal to noise ratio and image quality is the time-of-flight technique, where fast scintillators with high stopping power are needed. Particle detectors in future high energy physics experiments will operate at high collision...

The TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy) facilities aims at gamma-ray astronomy at energies from a few TeV to several PeV, as well as cosmic ray physics from 100 TeV to several EeV. Combination of the wide angle Cherenkov timing detector TAIGA-HiSCORE with the 4-m class Imaging Atmospheric Cherenkov Telescopes (TAIGA-IACT) of FoV of 10x10 degrees...

The Tile Detector is a dedicated timing detector system developed for the Mu3e experiment, which is designed to search for the lepton-flavour violating (LFV) decay $\mu \rightarrow eee$ with a target sensitivity of $10^{-16}$. In order to determine the vertex of the three decay electrons, precise spatial and timing measurements are necessary, resulting in the requirement of a time resolution...

The ENUBET ERC project (2016-2021) is studying a narrow band neutrino beam where lepton production could be monitored at single particle level in an instrumented decay tunnel. For this purpose we have developed a specialized shashlik calorimeter with a compact readout. The modules are composed of 1.5 cm thick steel absorbers coupled to 5 mm thick plastic scintillators. A matrix of 3 x 3 fibers...

We report on the recent activity of the NA64 experiment at the SPS of CERN. The NA64 experiment uses a beam dump setup to conduct missing energy searches with a high intensity electron beam.
In 2016$\,$-$\,$2018 separate dedicated searches for two mediators between standard model and dark sector, a new light vector boson A' and a new short-lived neutral boson X, were performed. The A' was...

In order to extend the dynamic range of Water Cherenkov Detector Array (WCDA) in Larger High Altitude Air Shower Observatory (LHAASO), another 1.5-inch photomultiplier tube (PMT) is placed aside the 8–inch PMT in each cell of WCDA. All these 1.5-inch PMTs, total 900, consist of the WCDA++ system. The performances of these 1.5-inch PMTs, with special designed di-output voltage divider, are test...

The Compressed Baryonic Matter (CBM) experiment will be one of the research pillars of FAIR (Darmstadt, Germany), which is currently under construction. High-intensity heavy-ions beams delivered by the SIS100 accelerator (FAIR Phase 1) will be used to explore the QCD phase diagram at high baryon densities. Interaction rates of up to 10 MHz on a fixed target will enable measurements at an...

The DAMIC (Dark Matter in CCDs) Experiment employs the active silicon of low-noise charge-coupled devices (CCDs) as a target to search for a variety of dark matter candidates with masses below 10 GeV. An array of seven 675-$\mu$m thick CCDs with a target mass of ~40 grams has been collecting data at SNOLAB since early 2017 and the next stage of the experiment, DAMIC-M, will be an array of CCDs...

nEXO is an experiment being designed to search for neutrino-less double beta decay in liquid Xenon. Excellent energy resolution is required for background rejection which in turns require excellent efficiency for the detection of scintillation photons. At the same time, the intrinsic radioactive background of component must be minimize which rules out using photo-multiplier tube (PMTs)....
