Abstract

Damping of longitudinal coherent bunched-beam oscillations is needed in SIS18 and SIS100 to stabilize the beam, prevent emittance growth and keep beam loss low during acceleration. In last year’s work several approaches of digital filters for beam-phase control have been examined. An FIR (finite impulse response) filter with 3 taps, cf. [1], has been successfully used at GSI in several machine experiments for a beam-phase control system and a longitudinal feedback system. In this report an alternative FIR filter approach based on derivative estimation leads to better results as it damps dipole oscillations within one oscillation period whereas the former filter approach unveils its full potential only after one oscillation period.
