A new sensor for the measurement of fluoride ions in dielectric gas mixtures has been developed. The sensor has been specifically designed to be installed at the RPC Closed Loop gas system in the CMS experiment at the Large Hadron Collider at CERN.
The sensor employs a plastic optic fiber (POF) coated with a SiO2-like thin film. F- ions attack the glass-like layer and alter the fiber...

Large volume RPC detectors for charged particles are widely used in HEP
experiments. For such detectors monitoring gas temperature and RH working
condition is important because they both can affect the performance of the
detector.
We propose a gas RH monitoring system, specifically suited for large scale
RPC detectors, based on fiber optic technology with use of Fiber Gragg
Grating...

Part of the experimental programs proposed for the R3B setup at the FAIR facility, requires a time-of-flight (ToF) measurement for the mass identification of ions in the large range of charges Z=1 to 92, at energies of several hundreds of MeV/u.
For flight paths about 15 m, the ToF measurement require resolutions well below 100 ps, and a detection surface of the order of 2x1 squared...

We report on the construction of a large scale prototype of a Digital
Hadron Calorimeter (DHCAL), utilizing Resistive Plate Chambers (RPCs)
with 1 x 1 cm^2 readout pads as the active medium. The design of the
calorimeter was optimized for the application of Particle Flow Algorithms
to the measurement of hadronic jet energies.
The calorimeter prototype measures about two cubic meter...

The Digital Hadron Calorimeter (DHCAL) is a large scale
prototype of an imaging calorimeter, using Resistive Plate
Chambers (RPCs) as active medium. The calorimeter counts
close to 500,000 readout channels.
In this talk we will present the measurement of the
performance parameters of the RPCs, i.e. the noise rate,
the MIP detection efficiency and the pad multiplicity.
The...

Large GRPC detectors equipped with semi-digital electronics readout and 1 cm2 lateral granularity were conceived to be used as a sensitive medium in the hadronic calorimeter of the future linear collider experiments. The GRPC detector was designed to provide high detection efficiency, excellent homogeneity and negligible dead zones. The readout electronics was developed to associate...

In this work we present results concerning in beam operation of the new Resistive Plate Chamber (RPC) Time of Flight (TOF) wall for the High-Acceptance DiElectron Spectrometer (HADES) spectrometer at GSI.
The new RPC-TOF wall, fully integrated in the spectrometer, has been successfully operated under final operation conditions corresponding to collision of Au + AU @ 1.25 GeV.

Resistive Plate Chambers are widely used in high energy physics
experiments as reliable trigger systems due to their excellent
time resolution and rate capability, while generally the track
spatial information is obtained by means of different
detectors. Studies show that it is possible to produce RPC with
good spatial resolution (~ 0.5 mm) by appropriate choice of the
pitch of the...

A 5-gaps timing RPC equipped with patterned electrodes coupled to both charge-sensitive and timing circuits yields a time accuracy of 80 ps along with a bidimensional position accuracy of 51 µm. These results were obtained over the full active area of 8x8 cm2 by calculating the straight-line fit residuals to the positions provided by a 3-layer telescope made out of identical detectors,...

The Compressed Baryonic Matter (CBM) experiment will be built at the new Facility for Antiproton and Ions Research (FAIR) in Darmstadt, Germany. This fixed target experiment will investigate Heavy Ion collision up to 35 AGeV for Au beams and 89 GeV for protons beams, with high interactions rates: up to 10MHz in Au+Au collision at 25 AGeV. To avoid the limitations of triggered systems at such...
