The ATLAS Level-1 Calorimeter Trigger uses reduced-granularity information from all the ATLAS calorimeters to search for high transverse-energy electrons, photons, τ leptons and jets, as well as high missing and total transverse energy. The calorimeter trigger electronics has a fixed latency of about 1 μs, using programmable custom-built digital electronics. This paper describes the Calorimeter Trigger hardware, as installed in the ATLAS electronics cavern.

Abstract The construction and testing of plastic streamer tubes for use as a large-area muon detector at OPAL are described. The use of extruded Noryl coated with a new carbon-loaded vinyl resistive paint is found to give tubes that behave in a uniform and reliable manner.
