| Abstract |
We measure the bunch length at BEPC II electron storage ring using a dual sweep streak camera at visible light diagnostic beamline. The impedances estimated by a series R+L impedance model. Resistive impedance of R=446±21 Ω is obtained by measuring loss factor from measured synchronous phase advancing with streak camera. An inductance impedance of L=23.3±1.8 nH has been estimated by measuring single bunch lengthening with beam current. Both loss factor and inductance are close to the impedance budget. Besides, the streak cam-era is also used to measure synchronous phase at low current as RF voltage changing from 0.85 MV to 1.65 MV.
