SDA time intervals

SDA (Sequenced Data Acquisition) Time Intervals is a hierarchical logging system for describing complex largescale repeated processes. SDA has been used extensively at Fermilab for fine tuning during Tevatron Collider Run II. SDA Time Intervals is a new system born during discussions between CERN and FNAL about routinely recording relevant data for the LHC. Its main advantages are extremely low maintenance and good integration with traditional flat dataloggers. The Time Intervals (TI) system records the time of key events during a process and relates these events to the data that a traditional datalogger archives.
