High-resolution TOF with RPCs
In this work, we describe some recent results concerning the application of Resistive Plate Chambers operated in avalanche mode at atmospheric pressure for high-resolution time-of-flight measurements. A combination of multiple, mechanically accurate, thin gas gaps and state-of-the-art electronics yielded an overall (detector plus electronics) timing accuracy better than 50 ps s with a detection...
متن کاملHigh-resolution timing of MIPs with RPCs } a model
Resistive Plate Chambers made with glass and metal electrodes forming accurately spaced gas gaps of a few hundred micrometers have reached timing accuracies below 50ps p with e$ciencies above 95%. This type of detector, operating at atmospheric pressure with non-#ammable gases, seems well suited for large-area TOF systems, providing performances comparable to the existing scintillator-based TOF...
متن کاملStereo Based Very High Resolution Satellite Image Classification Using Rpcs
Detection of urban objects in very high resolution (VHR) satellite imagery is challenging due to the similarities in the spectral and textural characteristics of urban land cover classes. Therefore, additional information such as elevation data is required for a proper classification. In this study, instead of LiDAR data, elevation information generated from satellite stereo images is used to a...
متن کاملHigh rate ( up to 105 Hz / cm 2 ) , high position resolution ( 30 m m ) photosensitive RPCs
In many applications there is a need for high position resolution VUV and UV imagers. For these applications we have developed and successfully tested 1D and 2D VUV imaging detectors based on microgap RPCs. Two versions of these detectors were extensively tested: one filled with photosensitive vapours and the other one with the GaAs cathode coated by a 400 nm thick CsI layer. The main feature o...
متن کاملSingle-gap timing RPCs with bidimensional position-sensitive readout for very accurate TOF systems
In this work, we report the development and performance of single-gap timing RPCs equipped with a 3mm FWHM resolution bidimensional position-sensitive readout and reaching a timing resolution of 55 ps s 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 provid...
