Abstract :
During 2014, upgraded-demonstrator electronics will be installed in a Tile calorimeter drawer to obtain long term experience with the redundant electronics proposed for a full upgrade scheduled for 2022.The new, FPGA-based system uses dense programmable logic, which must be proven to be sufficiently radiation tolerant. It must also be protected against radiation induced single event upsets that can corrupt memory and logic Radiation induced errors need to be detected and compensated for in time to minimize data loss, and also to avoid permanent damage. Strategies for detecting and correcting radiation induced errors in the Kintex-7 FPGAs on the Demonstrator electronics are evaluated and discussed.
