Silicon Photomultipliers (SiPMs) are highly sensitive solid-state photodetectors consisting of a 2D array of small-size Avalanche Photodiodes (APDs) working in Geiger mode, connected in parallel and joined together on a common silicon substrate.
They have extraordinary features of high sensitivity down to single-photon level, fast timing and high dynamic-range while maintaining low-voltage...
The increasing interest for Silicon PhotoMultipliers (SiPMs) in Astroparticle Physics applications is due to several attractive features compared to the other detectors like Photo Multiplier Tubes (PMT). The great advancement in solid-state technology allowed SiPMs to have a higher Photo Detection Efficiency (PDE) in the near ultraviolet (NUV) region, a fast response, single photon sensitivity...
The interaction between gamma-ray photons and the Earth atmosphere generates air showers composed of very high-energy particles which, moving through the air, generate Cherenkov light flashes. These flashes can be detected to study astronomical sources emitting very high-energy gamma rays in the TeV energy range.
Here, we present the camera design adopted for the nine innovative dual-mirror...
The Photon Detection System (PDS) of the first two DUNE far detectors (FD1 and FD2) is composed of 6000 and 672 photon detection units respectively, named X-Arapuca.
The PDS will complement and boost the DUNE LArTPC for the detection of non beam events: the prompt light detection will enable the trigger and the calorimetry of the supernova neutrinos, and improve the vertex reconstruction of...
The iTOP detector is a Cherenkov detector specialized on particle identification at Belle II. The SuperKEKB accelerator collides electrons and positrons with a design luminosity of 6*10^(35)/(cm^2 s). In order to exploit the high collision rate Belle II has a trigger rate of up to 30 kHz.
The iTOP detector uses quartz bars as the source of Cherenkov photons. The photons are reflected inside...
With the start of LHC Run 3 the LHCb experiment is designed to run at an instantaneous luminosity five times larger with respect to previous running periods, aiming to collect $\text{L}=50~\text{fb}^{-1}$ of $pp$ collisions data by the end of Run 4. In addition, thanks to a trigger-less readout and a full software trigger, the selection efficiency for fully hadronic decay channels of heavy...
The TORCH (Time Of internally Reflected Cherenkov light) detector is proposed for the high-luminosity Upgrade-II of the LHCb experiment, with planned start-up after 2033. The aim of TORCH is to measure time-of-flight with a 15 ps resolution per charged-particle track, providing particle identification over the momentum range 2-15 GeV/c. TORCH is to be located approximately 9.5m downstream of...
To ensure the necessary precision for the $K^+ \rightarrow \pi^+ \nu \bar\nu$ analysis, the NA62 kaon identification detector is required to have a time resolution better than 100 ps, at least 95% kaon tagging efficiency, and a pion mis-identification probability of less than $10^{−4}$. For the data collected so far, the tagging of kaons in the NA62 beam has been performed with a Cherenkov...
A novel single-photon detector based on a vacuum tube with transmission photocathode, microchannel plates and the Timepix4 CMOS ASIC used as read-out anode is presented. Timepix4, developed by the Medipix4 Collaboration, consists of a 512x448 pixel matrix with 55 microns pitch. Each pixel is equipped with amplifier and discriminator, and a TDC allows for precise measurement of the hit...
A modified Depleted P-Channel Field Effect Transistor (DEPFET) providing non-linear signal response is the distinctive feature of the 1 Mpixel DSSC camera, aiming at ultra-fast imaging of soft X-rays at the European XFEL. The calibration of the non-linear DEPFET-based readout is the key to reach simultaneously both single-photon resolution and high dynamic range but it is also the major...
