The ICARUS-T600 detector at LNGS is the first large mass Liquid Argon TPC (LAr-TPC) going into operation in an underground laboratory.
In the development of the electronics, a particular effort has been addressed to study and implement an on-line hit finding algorithm, for the definition of regions of interest (ROI). This feature has shown to be sensitive to small charge depositions (~1 MeV)...

The COMPASS digital trigger system is an FPGA based real time trigger logic which detects event signature by analyzing already digitized detector information. The trigger system has distributed multi stage architecture. The first stage is implemented in front-end electronics and it runs in parallel to data acquisition. The COMPASS event selection criteria are based on event geometry, extracted...

The electromagnetic calorimeter (EMCAL) of ALICE is a large acceptance calorimeter that will enhance the capabilities for jet measurement. Based on the previous development made for the Photon Spectrometer (PHOS) level-0 trigger, a specific electronic upgrade was designed in order to allow a fast triggering on high energy jets (level-1). This development was made possible by the use of the...

The ATLAS first-level calorimeter trigger is a hardware-based system designed to identify high-pT jets, electron/photon and tau candidates and to measure total and missing ET in the ATLAS calorimeters. After more than two years of commissioning in situ with calibration data and cosmic rays, the system has now been extensively used to select the most interesting proton-proton collision events....

The ATLAS Level-1 Calorimeter Trigger (L1Calo) is a fixed latency, hardware-based pipelined system designed for operation at the LHC design luminosity of 10^34cm-2s-1. Plans for a several-fold luminosity upgrade will necessitate a complete replacement for L1Calo (Phase II).
But backgrounds at or near design luminosity may also require incremental upgrades to the current L1Calo system (Phase...

The upgrade of the LHC towards luminosity beyond the design value requires improved L1 trigger selectivity in order to keep the maximum total trigger rate at 100 kHz. In the ATLAS L1 muon trigger system this necessitates an increase of the pT threshold for single muons. Due to the limited spatial resolution of the trigger chambers, however, the selectivity for tracks above ~20 GeV/c is...

The existing three-level ATLAS trigger system is deployed to reduce the event rate from the bunch crossing rate of 40 MHz to ~200 Hz for permanent storage at the LHC design luminosity of 10^34 cm^-2 s^-1. When the LHC reaches beyond the design luminosity, the load on the Level-2 trigger system will significantly increase due to both the need for more sophisticated algorithms to suppress...
