Description

Beam-coupling impedances (Z) for the 7-GeV APS storage ring have been numerically estimated. In order to confirm these calculations, the wire method with a synthetic pulse technique was used to measure the beam coupling impedance of various vacuum components around the main storage ring. A section of the beam+antechambers, a vacuum isolation valve with and without the RF shielding screen, an insertion device, and a photon absorber were used as a device under test (DUT) to obtain the results. The results were compared with the computer simulations and the Z or k-dependence on bunch lengths was studied.
