In 2009 COMPASS performed a test measurement of neutral Primakoff reactions, characterized by high energetic photons in one of the two electromagnetic calorimeters. Back then a digital trigger had been implemented to the existing readout electronics in order to detect these events. For 2012 a long measurement of these processes is foreseen. In order to extend the cinematic range to lower...

Modern experiments at hadron colliders search for extremely rare processes hidden in much larger background levels. As the experiment complexity and the accelerator backgrounds and luminosity increase we need increasingly complex and exclusive selections. The FastTracker (FTK) processor for the Atlas experiment offers extremely powerful, very compact and low power consumption processing units...

The ALICE experiment at the LHC is equipped with an electromagnetic calorimeter (EMCal) designed to enhance its capabilities for jet measurement. In addition, the EMCal enables fast triggering on high energy jets and high pt photons with a multiplicity dependent threshold. After its commissioning in 2010, the EMCal L1 trigger has been officially approved for physics data taking in 2011....

The NA62 experiment at the CERN SPS aims to measure the Branching Ratio of the very rare kaon decay K+ -> pi+ nu nubar collecting ~100 events with a 10% background in two years of data taking. To reject the K+ -> pi+ pi0 background the NA48 liquid krypton calorimeter will be used in the 1-10 mrad angular region. A vertical slice of the trigger processor has been assembled and tested in the...
