The Trigger of the Dimuon Arm: Architecture and Detectors

The trigger system of the ALICE dimuon arm is based on Resistive Plate Chambers (RPC). Besides a short description of the trigger system, the test results of an RPC prototype with electrodes made of low resistivity bakelite (~3.10<SUP>9</SUP>cm) are presented. Rate capability, time resol...

Descripción
Sumario:The trigger system of the ALICE dimuon arm is based on Resistive Plate Chambers (RPC). Besides a short description of the trigger system, the test results of an RPC prototype with electrodes made of low resistivity bakelite (~3.10<SUP>9</SUP>cm) are presented. Rate capability, time resolution and cluster size have been measured for the RPC operated both in streamer and in avalanche mode. Although the rate capability is obviously higher in avalanche mode (few kHz/cm<SUP>2</SUP>), remarkable results have been achieved even in streamer mode (several hundreds of Hz/cm<SUP>2</SUP>).
