Abstract
The ALICE detector is a dedicated heavy-ion detector at the Large Hadron Collider which is commissioned end of 2007 at CERN. The ALICE triggers are handled by the Central Trigger Processor and distributed to all sub-detectors, amongst other the Time Projection Chamber and the Photon Spectrometer. The Front End Electronics of the Time Projection Chamber and the Photon Spectrometer share many of the same components. The Photon Spectrometer provides the trigger system with level 0 and level 1 triggers (e.g., high- ${\rm p}_{\rm t}$ photons) by the use of several Trigger Router Units and a Trigger-OR board. The trigger electronics and the Front End Electronics are situated close to the collision-point, and errors due to radiation effects are to be expected.
