| Abstract | Synchro-beta side band caused by electron cloud instability has been observed at KEK-B factory. The side-band appears between $ν<strong>β+ν</strong>s$ and $ν<strong>β+2ν</strong>s$ above the threshold of beam size blow up and disappear by applying solenoid field. The side-band is an evidence of strong head-tail instability caused by electron cloud. The side-band is characterized by positive shift, $+1-2ν<strong>s$, while general strong head-tail instabilities give frequency with negative shift $ν</strong>beta-ν_s$. We study the synchro-beta spectrum using a code, PEHTS, which simulates single bunch electron cloud instability. |
