Trigger electronics for the ALICE PHOS detector

The Photon Spectrometer of ALICE consists of 5 identical modules of 56 multiplied by 64 PWO crystals with a total of 100 degree azimuthal coverage of the barrel. The electronics required for implementing both the L0 trigger for high luminosity p-p physics and the L1 trigger for high p//T Pb+Pb physi...

description The Photon Spectrometer of ALICE consists of 5 identical modules of 56 multiplied by 64 PWO crystals with a total of 100 degree azimuthal coverage of the barrel. The electronics required for implementing both the L0 trigger for high luminosity p-p physics and the L1 trigger for high p//T Pb+Pb physics has been studied. A full integration of the trigger logic into the detector's enclosure is based on analog transmission of fast trigger sums between stacks of front-end boards and trigger-router units. The latter contain 112 digitizer channels of 10bit, which are mapped into a single FPGA per trigger unit, covering areas of 24 multiplied by 16 crystals. The running modes allow for Level-0 trigger at 800ns and Level-1 at 6200ns trigger latencies. The design and status of the PHOS trigger electronics are outlined.
