Implementation of the data acquisition system for the resistive plate chamber pattern comparator muon trigger in the CMS experiment

چکیده
This paper presents the implementation of the data acquisition system of the resistive plate chamber (RPC) subdetector in compact muon solenoid (CMS) experiment at the Large Hadron Collider (LHC) in CERN. The described readout system connects with the RPC detector, the RPC link system, the RPC trigger system and the CMS data acquisition system and creates one of multiple metrological systems in CMS experiment. The readout system receives the data provided by the multiple channels of the link system, filters out the non-triggered data, encapsulates the data into the standard CMS common data format events and sends them to the global data acquisition system. The main problem in the readout system design was to provide the sufficiently large throughput to reliably transfer the data. The implemented system is the scalable solution based on advanced Field Programmable Gate Arrays (FPGA) technology.

متن کاملBeam Test Results on Resistive Plate Chambers for the CMS Experiment
Resistive Plate Chambers were tested in a muon and a pion beam to study the performances at different running conditions. Results on a first chamber built without the linseed oil treatment of the bakelite surfaces are presented together with an evaluation of the local effects due the spacers. These results are extrapolated to the conditions expected at LHC.
متن کاملA Highly Selective First-Level Muon Trigger With MDT Chamber Data for ATLAS at HL-LHC
Highly selective triggers are essential for the physics programme of the ATLAS experiment at HL-LHC where the instantaneous luminosity will be about an order of magnitude larger than the LHC instantaneous luminosity in Run 1. The first level muon trigger rate is dominated by low momentum muons below the nominal trigger threshold due to the moderate momentum resolution of the Resistive Plate and...
