Abstract

The ELETTRA/SLS transverse multi-bunch feedback is a bunch-by-bunch system using state-of-the-art DSPs (digital signal processors) for the processing of the position data coming from all of the 432/4.80 2ns-spaced bunches. While a number of DSPs execute the feedback algorithms, the rest of them are dedicated to the real-time analysis of all the sampled bunch positions stored in up to 96 Mbytes of memory allowing time and frequency domain analysis with unprecedented depth and resolution. In addition to the advantages of feedback digital filtering, such as flexibility and reproducibility, this novel integrated mixing of functionalities opens the way to the implementation of a number of features that enhance system operability and the quality of the beam
