|WEPME002||Fast Orbit Feedback at BESSY-II: Performance and Operational Experiences||2920|
At the 3rd generation light source BESSY II the first phase of a fast orbit feedback system(*) has been completed and put into operation in 2012. In this first phase the aim was to achieve noise suppression in the 1Hz to several 10Hz range, mostly avoiding expensive upgrades to existing hardware, such as beam position monitors and the CAN based setpoint transmission to the power supplies. Only the power supplies were replaced with newer, faster versions. This paper describes the capability of the phase-I FOFB with respect to beam motion transient suppression, low frequency damping and high frequency noise generation as well as aspects of operational integration and stability.
