RPC operation at high temperature
The resistive electrodes of RPCs utilised in several current experiments (ATLAS, CMS, ALICE, BABAR and ARGO) are made of phenolic/melaminic polymers, with room temperature resistivities ranging from 10 O cm; for high rate operation in avalanche mode, to 5 10 O cm; for streamer mode operation at low rate. The resistivity has however a strong temperature dependence, decreasing exponentially with ...
متن کاملA model for RPC detectors operating at high rate
We present a simple model to describe the behavior of Resistive Plate Chambers (RPC) exposed to a high particle flux. We show that the RPC current, I ; saturates at large flux values and we explain why the dependence of I on the applied voltage V0 is essentially linear. We show that in the saturated regime the current is controlled by the value of the bulk electrode resitivity, r; which is dire...
متن کاملCharacteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...

We believe that the future of marine sensing lies in teams of cooperative autonomous assets working together to provide a coherent picture of the operating environment. The assets may be fixed or mobile platforms, both underwater and on the surface. Although several different research projects at ARL contribute important technologies towards achieving this vision, the STARFISH research program ...
متن کاملRPC performance at KLM/BELLE
The RPC detectors in the KL-muon (KLM) subsystem of the Belle detector and their performance are described in this paper. The Belle RPCs are built using glass electrodes. This system has operated stably with very high detection efficiency and low dark current since June 1, 1999. r 2003 Elsevier Science B.V. All rights reserved. PACS: 29.40.Cs; 07.05.Hd
