The characterization in the VUV range of reflectivity, diffusivity and transmittivity of various components plays a crucial role in understanding and optimizing the performance of particle detectors exploiting the scintillation light coming from liquefied noble gases.
To this purpose a goniometric measurement system has been realized. The light produced by a deuterium lamp is wavelength...
The ePIC experiment at the Electron-Ion Collider (EIC) includes a dual-radiator RICH (dRICH) detector for PID in the forward region. The dRICH will be equipped with 3x3 mm2 silicon photomultipliers (SiPM) for Cherenkov light detection over a surface of ~3 m2 (~300k readout channels), representing the first HEP application of SiPMs for single-photon detection. SiPMs are chosen for their low...
Time-of-Flight Mass Spectrometry (ToFMS) is a well-established technique used to identify, discover and quantify compounds in a sample and to study the structure and chemical properties of molecules. It has a wide range of applications in different fields like proteomics, drug development, environmental analysis/monitoring, space exploration or forensic analysis. In ToFMS the sample under...
Silicon Drift Detectors (SDDs) are integral to X-Ray Fluorescence (XRF) spectrometry. They are vital for non-destructively analyzing cultural heritage samples. Traditionally, these detectors have used beryllium windows to maintain vacuum and protect the sensor. However, beryllium windows are not transparent to low energy X-rays. This opacity restricts the ability of SDDs to measure oxygen’s...
Scintillators are among the most common detectors employed for characterization and spectroscopy of a wide variety of radiations, with applications ranging from cosmic-ray experiments to nuclear medicine. Quenching effects degrade the scintillation light yield proportionality, inevitably affecting the instrument performance and posing a layer of complexity to its precise calibration. Detailed...
The J-PARC E50 experiment aims for charmed baryon spectroscopy utilising the high-momentum secondary particle beam line (π20) at the J-PARC hadron experimental facility. Charmed baryons(𝑌𝑐∗+) will be produced in the reaction 𝜋− + 𝑝 → 𝐷∗− + 𝑌𝑐∗+ with a beam momentum of 20 GeV/c. The charmed baryons will be identified by reconstructing 𝐷∗− from its decay particles (𝐾+ 𝜋− 𝜋−) and calculating the...
Synchrotron radiation facilities serve as crucial interdisciplinary research platforms, with the performance and operational efficiency closely tied to the quality of the employed detector technology. The Silicon Drift Detector (SDD) is characterized by high count rates, and superior energy resolution, which has led to its widespread application in synchrotron radiation spectroscopy...
One of the main challenges of the near-future high-energy physics experiments will be the dramatic increase of the spatial density of particle collisions and the need to carry also precise timing information with silicon detectors to perform an accurate reconstruction of tracks. To cope with such requirements one of the recent developments exploits the integration of the Low Gain Avalanche...
The Photon Detection System is a crucial component of the ICARUS detector in the Short Baseline Neutrino (SBN) Program at Fermi National Accelerator Laboratory (FNAL). It consists of 360 Photo Multiplier Tubes (PMTs) 8” Hamamatsu 5912-MOD and, since June 2020, it has been operated at the liquid Argon cryogenic temperature. During these years, the PMTs have shown gain losses as an aging...
Recently, sub-millimetre cadmium zinc telluride (CdZnTe or CZT) linear array detectors for high-flux spectroscopic X-ray imaging are proposed and fabricated by our group. These activities, in the framework of a PRIN-MUR project, plan the development of room temperature X-ray scanners for contaminant detection in food industry. As widely demonstrated, CZT is one of the key materials for the...
We have proposed a method of constructing large-area MCPs by stacking thin, patterned laminae on edge to form laminar MCPs (LMCPs$^{\rm{TM}}$) with applications in gamma ray detection for TOF-PET and high-energy physics experiments. The laminae are first patterned with channels of arbitrary shape and size so that when stacked, they form pores as in a traditional MCP. Since the laminae are...
The LHCb experiment is one of the four large detectors at the Large Hadron Collider (LHC) accelerator at CERN, performing searches for new physics through studies of CP-violation and decays of heavy-flavour hadrons.
The RICH (Ring Imaging Cherenkov) detectors play a key role in particle identification.
An intense R&D programme to look for suitable candidates for the planned LHCb Upgrade II...
The INFN Roma1 group has designed a new structure of all-in-one scintillator particle detectors, ArduSiPM, exploiting the latest innovations in silicon photomultiplier (SiPM) and System on Chip (SoC) technology.
We have minimized the external components to the analog ones, using intensively the internal peripherals of the microcontroller, making these devices compact and high-performance....
The COMET (COherent Muon to Electron Transition) experiment searches for a muon-to-electron conversion with muonic aluminium in which a muon is captured in an orbit instead of an electron. This process violates the conservation law of charged lepton flavour and is forbidden in the standard model of particle physics. If discovered, this would be clear evidence of the new physics. In the first...
Percival is a two-megapixel CMOS imager designed for the photon science community. It has a large, contiguous imaging area with many small pixels (4x4 cm2, 27x27 um2 pixels), high frame rate suitable for high-luminosity experiments and conventional FELs (design frame rate 300 Hz, proportionally faster in ROI operation), and dynamic range spanning single photon discrimination at 250 eV (noise...
Because of its superior timing resolution, low dark noise, and stability in magnetic fields, the Microchannel Plate Photomultiplier Tube (MCP-PMT) is an essential component of particle identification detectors like PANDA, LHCb and Belle II, as well as fast neutron or x-ray detections in nuclear inertial confinement fusion (ICF) experiments and laser communication. However, there is more work...
For the particle identification systems of the future high energy physics detectors, single photon sensors with sub-mm granularity and high sensitivity are needed. Due to harsh radiation environments and high track densities, they must be resilient to neutrons and have excellent timing resolution. For example, in the LHCb RICH after Upgrade 2, the expected fluence will be 3x10$^{12}$ neq...
MEG II, the upgrade of the MEG experiment, has run physics data acquisition since 2021, collecting $7.3 \times 10^{14}$ $\mu^+$ on target during 42 weeks of DAQ live time. It searches for the Lepton Flavor Violating Decay $\mu^+ \to e^+ \gamma$ with sensitivity improved by an order of magnitude from MEG that had set the current upper limit on the branching ratio ${\mathcal B}(\mu^+ \to e^+...
The improvement of the timing performance is one of the main focus for several fields from high energy physics to biomedical applications such as Time of Flight Positron Emission Tomography (ToF-PET). In the last years, excellent results in terms of Single Photon Time Resolution (SPTR) and Coincidence Time Resolution (CTR) have been achieved thanks to the improvement of the scintillator...
Large Area Picosecond PhotoDetectors (LAPPDs) are photosensors based on MicroChannel Plate (MCP) technology with about 400 cm2 sensitive area. The external readout plane of a capacitively coupled LAPPD can be segmented into pads providing a spatial resolution down to 1 mm scale. The LAPPD signals have about 0.5 ns rise time followed by a slightly longer fall time and their amplitude reaches a...
