Single-gap timing RPCs with bidimensional position-sensitive readout for very a...
Blanco, A.; Ferreira-Marques, R.; Finck, Ch.; Fonte, P.; Gobbi, A.; Policarpo, A.In this work, we report the development and performance of single-gap timing RPCs equipped with a 3 mm FWHM resolution bidimensional position-sensitive readout and reaching a timing resolution of 55 ps [sigma] at an efficiency of 75% for MIPs. These chambers are aimed to be applied in a multilayer geometry, forming small and very accurate TOF systems. The avalanche localization capability would provide informat...
A large area timing RPC
Blanco, A.; Ferreira-Marques, R.; Finck, Ch.; Fonte, P.; Gobbi, A.; Policarpo, A.; Rozas, M.A large area Resistive Plate Chamber (RPC) with a total active surface of 160×10 cm2 was built and tested. The surface was segmented in two 5 cm wide strips readout on both ends with custom, very high frequency, front-end electronics. ; http://www.sciencedirect.com/science/article/B6TJM-44JHY5B-8/1/909cdae0fda12f2c09d271fc07f60f5b
Development of large area and of position-sensitive timing RPCs
Blanco, A.; Marques, R. Ferreira; Finck, Ch.; Fonte, P.; Gobbi, A.; Mendiratta, S. K.; Monteiro, J.; Policarpo, A.; Rozas, M.Resistive Plate Chambers (RPC) made with glass and metal electrodes forming accurately spaced gas gaps of a few hundred micrometers have reached timing accuracies below 50 ps [sigma] with efficiencies above 99% for MIPs. This type of detector, operating at atmospheric pressure with non-flammable gases, seems well suited for large TOF systems, providing performances comparable to the scintillator-based TOF techn...
