Description
Direct Diode Detection (DDD) tune measurement was developed for the Large Hadron Collider, has been used at many hadron machines over the last many years, and has recently been implemented in electron machines as well. This method provides orders of magnitude greater sensitivity to betatron oscillations than conventional beam position measurement approaches. In order to measure the tune throughout the full acceleration ramp using conventional beam position approaches in the BESSY II Booster, a fast-ramping electron synchrotron, it is necessary to use external excitation which is large enough that it disturbs injection into the storage ring and reduces top-up injection efficiency. Implementation of the DDD tune measurement system in the Booster allows for tune measurements during the entire ramp with little to no external excitation and therefore no disturbance to top-up operation.
