Abstract
his document surveys the RPC-based detection systems of running and future collider experiments focusing on the implications of the choice of some basic detector features: number of gaps, electrode material and operating mode. The muon identification systems of the B-factory experiments BaBar and Belle is described and the RPC performance since the first operation of the detectors is briefly reported. The trigger systems of the future LHC experiments ALICE, ATLAS and CMS are discussed and some results obtained in the research and development programs carried out by the Collaborations are reported
Highlights
Resistive plate Chambers (RPCs) [1] are parallel plate gaseous detectors that outstand for their excellent time resolution and the relatively low production cost per unit area
The new RPCs installed in the outermost layers, which are subject to the highest radiation flux, started showing significant increase in dark current and declining efficiency after 140 days of operation
A survey of the RPC-based systems in running and future experiments has been presented in this document
Summary
Resistive plate Chambers (RPCs) [1] are parallel plate gaseous detectors that outstand for their excellent time resolution and the relatively low production cost per unit area. These characteristics make them good candidates in any high energy physics experiment demanding large and fast detecting surfaces with space resolutions of the order of the cm. A proper choice of the RPC structural parameters allows to tune the detector in terms of time and space resolution, rate capability and intrinsic noise. Single and double gap (∼ 2 mm wide) RPCs have a time resolution of a few ns They can be used for the large muon identification and triggering systems of experiments at colliders.
