The ALICE Time-Of-Flight (TOF) detector is a cylindrical array with a total area of around 150 m2 and more than 150000 readout channels, covering the whole barrel region; it will identify pions and kaons up to 2.5 GeV/c and protons up to 4 GeV/c extending the ALICE PID capabilities to higher momenta. This performance requires a total time resolution of about 100 ps which is achieved by means...

A large-area (50 m^2) Time of Flight system has recently beeninstalled in the STAR Experiment at RHIC. The detectors are Multigap Resistive Plate Chambers (MRPCs) and are digitized using custom electronics based on the CERN "NINO" and "HPTDC" chips. Several different prototype systems were built and operated in STAR from
2003 to 2005. The design and performance of the prototypes, as well as...

In this work we present results concerning the ground-level cosmic ray test, prior to the final installation and commissioning of the new Resistive Plate Chamber (RPC) Time of Flight (TOF) wall for the High-Acceptance DiElectron Spectrometer (HADES) spectrometer at GSI [1].
The TOF wall is composed of six equal sectors, each one constituted by 187 individual 4-gaps glass-aluminum shielded RPC...

We report on the performance of the FOPI Time-of-Flight (ToF) Barrel in a Heavy-Ion (HI) collision experiments. The Barrel is made out of Multi-strip Multi-Gap Resistive Plate Counters (MMRPC), where each counter has 16 strips with the pitch of 2.54 mm. Strips are 90 cm long and read out from both sides. With such system we have repeatedly obtain the ToF resolution better than 95 ps. The...

The commissioning of the Time-of-Flight (TOF) detector of ALICE has been carried
out and the apparatus is presently fully operational. With a high-statistics calibration
the detector is expected to provide pi/K and K/p identification up to a momentum of
2.5 GeV/c and 4.0 GeV/c respectively for charged particles.
The Multigap Resistive Plate Chambers (MRPC) are the base element of ALICE...

Preliminary tests of the ALICE Time-Of-Flight (TOF) system components, built of numerous MRPC strips, were not possible with beam particles and extensively involved cosmic measurements. For this purpose, a Cosmic Ray Test Facility (CRTF) was specially constructed, built and put into action at CERN. It represents a two-layer telescope of Scintillation Tiles with MRS APD Light Readout, provides...
