摘要

2014年期间，升级后的演示电子设备将安装在瓦片式热量计抽屉中，以获得冗余电子设备的长期经验，计划于2022年进行全面升级。新的基于fpga的系统使用密集的可编程逻辑，必须被证明具有足够的耐辐射能力。它还必须防止辐射引起的单事件干扰，这可能会破坏内存和逻辑。辐射引起的错误需要及时检测和补偿，以尽量减少数据丢失，并避免永久性损坏。评估和讨论了在演示电子设备上检测和纠正Kintex-7 fpga辐射诱导误差的策略。

Radiation tolerance and mitigation strategies for FPGA:s in the ATLAS TileCal Demonstrator

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.
