  • Abstract
    HOM damped normal conducting passive harmonic cavities are developed and installed at the BESSY II storage ring. The mechanical and electrical parameters and the operation modes are described. The operational parameters are presented, showing good agreement of bunch lengthening, synchrotron frequency shift and increase of Touschek lifetime. Measured data of the transient shift of the synchronous phase driven by the harmonic cavities are presented. Due to the HOM dampers no coupled bunch modes of the beam are driven by the harmonic cavity.
