Ultra-low mass drift chambers, with Helium-based gas mixture and high wire density are ideal trackers for high-precision experiments in the intensity frontiers of particle physics. In the search for Lepton Flavor Violation the MEG~II experiment at the Paul Scherrer Institut represents the state of the art in the search for the $\mu^+~\rightarrow~e^+~\gamma$ decay. The Cylindrical Drift CHamber...
An Ion Beam Facility (IBF) has been set-up at the INFN laboratory in Pisa with specific intent of having a test bench for studying gas detectors that detect low-energy ionizing radiation under low-pressure conditions (100 mbar and below).

The extension of the BESIII experiment (IHEP, Beijing) till 2030 prompted a program to improve both the accelerator and the detector. In particular, the current inner drift chamber suffers from aging and it is proposed to replace it with a detector based on cylindrical GEM technology.

For the operation at HL-LHC, the MDT chambers of the inner barrel layer (BIS) of the ATLAS muon spectrometer will be replaced by small-diameter Muon Drift Tube (sMDT) chambers which will be integrated with triplets of thin-gap RPC chambers in order to improve the acceptance and robustness of the barrel muon trigger system.
The sMDT chambers have half the drift tube diameter of the MDT...

Gaseous detectors are versatile devices that, despite their longevity, have known recently increasing fields of application, namely in the demanding rare-event search large-scale experiments. This recent increase in popularity can mostly be accounted by their capability to accommodate the features required by these experiments. One of these features is tracking which allows for particle...
The spherical proportional counter is a versatile gaseous detector with applications from direct dark matter searches to neutron spectroscopy. The multi-anode sensor ACHINOS has been transformative to the capabilities of the spherical proportional counter by enabling higher pressure operation and larger detectors. Another advantage is the additional event localisation capability brought by...
The Imaging X-ray Polarimetry Explorer (IXPE) represents the current state-of-the-art of astrophysical X-ray polarimetry.

Muography is a technique employed for object scanning using muons by analyzing their interaction with the scanned object. This interaction involves various mechanisms, with absorption and multiple Coulomb interactions being the most dominant. Muography offers non-destructive, radiation-free sub-surface imaging due to high penetration power of readily available cosmic muons.
The muography...
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory will collide polarized electrons with polarized proton/ions. The electron – Proton / Ion Collider (ePIC) Experiment is the EIC general-purpose detector aiming at delivering the full physics program of the EIC. This unique environment imposes stringent requirements on the tracking system needed for the measurement of the...
RPC detectors were already used in the past to perform the muon scattering tomography of several materials with high atomic number. RPCs are indeed well suited for muographic techniques since they can be built at relatively low cost, covering large areas with high efficiency, spatial and time resolutions. However, the front end electronics has a considerable impact on the detector cost,...
The current operation of the Resistive Plate Chamber (RPC) system within the CMS experiment involves approximately 95% tetrafluoroethane (C2H2F4, TFE). However, in response to climate change concerns, the European Union has instituted a ban on TFE owing to its elevated Global Warming Potential (GWP), resulting in an associated increase in market prices. In this framework, shared endeavors...
The ATLAS muon spectrometer will face an increase of particle rate consequently of the larger instantaneous luminosity for the high luminosity LHC phase (HL-LHC), expected to reach 7.5 x 10^34 cm^-2 s^-1.
Micromegas chambers are used in the New Small Wheel, the first end-cap muon spectrometer station, in order to provide good tracking and triggering performance at the intense particle rates...
The PICOSEC Micromegas (MM) detector is a precise-timing gaseous detector based on a Cherenkov radiator coupled with a semi-transparent photocathode and a MM amplifying structure, targeting a time resolution of tens of picoseconds for minimum ionising particles.

The current RPC system is undergoing a major upgrade, consisting in the installation of approximately 1000 RPC detector units of new generation in the innermost barrel layer of the ATLAS Muon Spectrometer. The goal of the project is to increase the detector coverage, currently limited to approximately 80%, and improve the trigger robustness and efficiency. The production of the gas volumes...
Particle detectors at the LHC experiments are very often characterized by large detector volumes and by the need of using very specific gases, some of which are greenhouse gases (GHGs). Given their high Global Warming Potential (GWP) and the increasingly stringent European regulations regarding the use and trade of these gases, CERN is today strongly committed to reduce GHGs emissions from...
The presented project aims to establish the use of single amplification stage resistive MPGD based on Micromegas technology, for a stable and efficient operation up to 10 MHz/cm2 particle rate.
