Bunch Charge (Feedback Loop) - Maintains bunch charge; requires Laser Power Set
Laser Power Set - Wakes up when Laser Power is changed, calculates and outputs to certain PVs in order to protect the camera. It is not a feedback loop
Transverse (Feedback Loop) - aka Trajectory, aka Launch; Includes the following Launch loops: Gun, Injector, Injector to Spect., X Cavity, L2, BSY, DL2, LTU, and UND
Longitudinal (Feedback Loop)
Start
- starts new instance of associated Controller loop thread
- starts with current actuator settings
- saves current actuator settings for future restore
Disable (pause)
- remembers last calculated actuator settings
- remembers running average used in integral term (longitudinal. only)
- Controller thread does not exit
Enable
- starts with new measurements, last calculated actuator settings,
- continues the running average used in integral term. (longitudinal. Only)
Stop
- Controller thread terminates after releasing its thread resources

• Complete stop, Controller loop thread exits and destroys its resources
