Description
With the transition from machine commissioning to beamline commissioning and user operation, long-term reliability and high availability of the SLS 2.0 accelerator complex have become critical. Rapid, systematic fault handling is essential to minimize downtime and protect the accelerator. This contribution presents the architecture and implementation of key systems developed for fault management at SLS 2.0, including the Post Mortem framework, Injection Guard, and controlled emergency beam-dump procedure. The Post Mortem system captures and logs comprehensive fault data for analysis supporting root-cause identification, confirmation of a successful emergency beam dump and continuous improvement. The Injection Guard ensures safe and reliable injection by monitoring critical parameters and preventing injection when safety thresholds are violated. For severe fault scenarios, a controlled emergency beam dump using a fast beam dump controller, a fast beam dump magnet and a dedicated beam dump protects sensitive components such as the vacuum chamber. Together, these measures form an integrated approach to fault handling that enhances operational robustness and user reliability. Initial experience during early user operation demonstrates their effectiveness and lays the foundation for further optimization and long-term reliability.
