Evaluation of ring impedance of the Photon Factory storage ring

Abstract

The loss parameters of the ducts in the Photon Factory (PF) storage ring were evaluated using the wire method and the code TBCI. Both the measurement and the calculation were done for a different bunch length ({sigma}) ranging from 23 to 80 ps. The PF ring impedance was estimated to be |Z/n|=3.2 {Omega} using the broadband impedance model. The major contribution to the impedance comes from the bellows and the gate valve sections. Improvements of these components will lower the ring impedance by half. (author).
