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 ...
A large area timing RPC prototype for ion collisions in the HADES spectrometer
Alvarez Pol, H.; Alves, R.; Blanco, A.; Carolino, N.; Eschke, J.; Ferreira-Marques, R.; Fonte, P.; Garzón, J. A.; González Díaz, D.; Pereira, A.We present a resistive plate chamber (RPC) prototype for time-of-flight measurements over large areas and at high occupancies, minimizing the inter-channel cross-talk. ; http://www.sciencedirect.com/science/article/B6TJM-4D75GPD-9/1/a6fe40c114a867a0f98e2fec0f133503
Performance of shielded timing RPCs in a 12C fragmentation experiment
Alvarez Pol, H.; Alves, R.; Blanco, A.; Carolino, N.; Eschke, J.; Ferreira-Marques, R.; Fonte, P.; Garzón, J. A.; González Díaz, D.; Pereira, A.We show the feasibility of large area timing RPC detectors for experiments dealing with fragmentation-like primary interactions and/or high detector multiplicities, without significative degradation of the detector capabilities. The tested prototype is constituted by three independent cells placed into grounded aluminium boxes, which reduce the cross-talk to the level of 0.4%. Each box consists of a 4-gap glass...
