Abstract

The NA62 experiment at CERN SPS aims to increase the precision in the measure of the Branching Ratio of the K⁺ → π⁺vv̅ decay. Efficient veto systems are needed to achieve the required background suppression level. The LKr, covering the angular range 1-10 mrad, is part of system vetoing photons due to π⁰ decay (from K⁺ → π + π⁰). This paper deals with the implementation of the LKr L0 trigger peak reconstruction algorithm on FPGA by using a mixed architecture based on soft core embedded processors together with custom VHDL modules. This solution allows an efficient and flexible reconstruction of the energy-deposition peak.
