Transverse Single Bunch Instability in PEP-X

PDF Version Also Available for Download.

Description

A proposed high-brightness synchrotron light source (PEP-X) is under design at SLAC. The 4.5- GeV PEP-X storage ring has four theoretical minimum emittance (TME) cells to achieve the very low emittance and two double-bend achromat (DBA) cells to provide spaces for IDs. Damping wigglers will be installed in zero-dispersion straights to reduce the emittance below 0.1nm. In this paper, we present a preliminary estimation of the threshold of the transverse mode coupling instability (TMCI). Three approaches have been used in the estimation and they agree well with each other.
