An analytical description of rate effects in timing RPCs
González-Díaz, D.; Fonte, P.; Garzón, J. A.; Mangiarotti, A.An analytical framework for describing the RPC behavior under high irradiation is proposed, including the effect of the fluctuations of the field. The description is compared with an equivalent MC and data for timing RPCs, showing good agreement. Moreover, the formalism allows to clearly identify the main variables ruling the process. ; http://www.sciencedirect.com/science/article/B6TVD-4KV4MR8-W/1/788b06292...
The effect of temperature on the rate capability of glass timing RPCs
González-Díaz, D.; Belver, D.; Blanco, A.; Marques, R. Ferreira; Fonte, P.; Garzón, J. A.; Lopes, L.; Mangiarotti, A.; Marín, J.In this study, we demonstrate a strong influence of the working temperature on the counting rate capability of large-area timing resistive plate chambers (RPCs) incorporating industrial flat glass electrodes. The effect relies on the sharp dependence of glass resistivity on temperature, approximately one order of magnitude for each 25 °C, allowing a considerable extension of the counting rate capability merely ...
Progress in timing Resistive Plate Chambers
Blanco, A.; Carolino, N.; Correia, C. M. B. A.; Ferreira-Marques, R.; Fonte, P.; Gobbi, A.; González-Díaz, D.; Lopes, M. I.; Lopes, L.; Macedo, M. P.Timing RPCs are Resistive Plate Chambers made with glass and metal electrodes separated by precision spacers. Typical gas gaps are a few hundred micrometers wide. Such counters were introduced in 1999 and have since reached timing accuracies below 50 ps [sigma] with efficiencies above 99% for MIPs. Applications in high-energy physics have already taken place with several more under study. ; http://www.scienc...
Resistive plate chambers for time-of-flight measurements
Blanco, A.; Fonte, P.; Lopes, L.; Mangiarotti, A.; Ferreira-Marques, R.; Policarpo, A.The applications of Resistive Plate Chambers (RPCs) have recently been extended by the development of counters with time resolution below 100 ps [sigma] for minimum ionising particles. Applications to HEP experiments have already taken place and many further applications are under study. In this work, we address the operating principles of such counters along with some present challenges, with emphasis on count...
