abstract = {Detecting anomalies in superconducting cavities at the
EuXFEL is essential for reliable operation. We began with a
model-based anomaly detection approach focused on residual
analysis. To improve fault discrimination, particularly for
quench events, we augmented the detection with a machine
learning-based classification. Key challenges are posed by
the transition to real-time operation, requiring
computational and integration adjustments. For the online
application, we deployed two servers at one of the 25
stations to detect and log anomalies with a software
implementation. In parallel, we pushed the development of a
firmware solution that will counteract critical faults in
real-time. At the current stage only the anomaly detection
is in online operation, which is planned to be augmented
with the online fault classification in the future. The
resulting detection system delivers reports across various
timescales, supporting both immediate responses and
long-term maintenance.},
