Abstract:

The aLIGO System Guardian provides a state-oriented framework for controlling the various aLIGO subsystems. State verification and transitions between states are handled by user-written scripts that are called automatically based on user input. Individual system guardians are overseen by guardian managers that can control the states of individual systems as well as those of the interferometer. This document provides an overview of the aLIGO System Guardian, as well as the tools needed for development for the different LIGO subsystems.
