The NA62 Liquid Krypton Electromagnetic Calorimeter Level 0 Trigger

The NA62 experiment at CERN SPS aims to measure the Branching Ratio of the very rare kaon decay K

νν̅ collecting O(100) events with a 10% background to make a stringent test of the Standard Model. One of the main backgrounds to the proposed measurement is represented by the K

decay. To suppress this background an efficient photo veto system is foreseen. In the 1-10 mrad angular region the NA48 high performance liquid krypton electromagnetic calorimeter is used. The design, implementation and current status of the Liquid Krypton Electromagnetic Calorimeter Level 0 Trigger are presented.
