Abstract
Abstract
The SuperKEKB is an electron-positron collider consisting of
two storage rings: the 4 GeV-positron low-energy ring and the
7 GeV-electron high-energy ring. The impedance of the rings has
been modeled using electromagnetic simulation codes and used to
study the single-bunch collective instabilities. The wake potentials
are exported from the impedance model and included in a particle
tracking simulation code, PyHEADTAIL. In this paper, we review the
impedance modeling and the results of the collective instability
simulations.
