Dr Sabrina GRASSINI (Politecnico di Torino)09/02/2012, 16:35New ideasoral presentationA 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...Go to contribution page

Dr michele caponero (enea; infn)09/02/2012, 16:55New ideasoral presentationLarge 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...Go to contribution page

Dr Enrique Casarejos (University of Vigo, Spain)09/02/2012, 17:35New ideasoral presentationPart 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...Go to contribution page

Dr Lei Xia (Argonne National Laboratory)09/02/2012, 17:55New ideasoral presentationWe 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...Go to contribution page

Jose Repond (Argonne National Laboratory)09/02/2012, 18:15New ideasoral presentationThe 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...Go to contribution page

Mr imad laktineh (ipnl)09/02/2012, 18:35New ideasoral presentationLarge 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...Go to contribution page

Mr Alberto Blanco Castro (LIP-Coimbra)09/02/2012, 18:55New ideasoral presentationIn 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. ...Go to contribution page

Dr Paolo Baesso (University of Bristol)10/02/2012, 09:00New ideasoral presentationResistive 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...Go to contribution page
