Readout System for the CMS RPC Muon Trigger
The CMS detector contains the RPC chambersa dedicated trigger subdetectorto identify muons, measure their transverse momenta pT, and determine the bunch crossing from which they originated.The RPC Muon Trigger algorithm is based on muon track search and classification in raw data from the RPC chambers. Large part of the RPC trigger electronics will reside in the control room (approx. 90 meters from the detector) where all trigger data are concentrated. Dedicated synchronous compression decompression algorithm is needed to sent all data for each bunch crossing via optical links. The RPC Readout system uses the same data as Trigger system and will be placed in the Trigger Racks. The idea of readout system and its limitations are discussed below. The paper includes description of prototype boards and tests in the synchronous CERN LHC like test beam H2 in May 2000.
Readout system for CMS RPC Muon Trigger
This paper presents readout for RPC based muon trigger system, part of CMS experiment on LHC collider at CERN (Geneva). All RPC data used to perform trigger algorithm are collected on RPC trigger boards of and send to general CMS data acquisition system. Zero suppression used to transfer data from detector to control room is used to decrease the amount the links and data to be stored.
Modeling of chemical reactors—XXIX mixing-cell model for packed bed reactors. Steady state considerations. Problems of multiplicity
Abstract The axial heat and mass transfer in tubular catalytic reactors may be described by mixing-cell model and diffusion model as well. The diffusion description yields for a strong exothermic reaction and adiabatic conditions three steady state profiles, on the other hand the mixing-cell model gives rise to more than three steady states. A simple numerical and graphical analysis for mixing-cell model is presented.
