Resources
Papers, presentations and links for the Signal Monitoring project, oldest material included. Several of the destinations are reachable only from inside CERN, and some of them describe tools that have since been retired — those are marked where they appear.
The module documentation for the earlier lhc-sm-api (Analysis, GUI, Metadata, DbSignal, pyeDSL, API Reference) is kept in the Signal Monitoring API archive.
Papers
The first entry is the account of the 2026 campaign, in which all mandatory and on-request powering tests were analysed automatically for the first time.
