  • Abstract
    We measured the longitudinal bunch shape by a streak camera at 2.5 GeV Pohang Light Source (PLS). The impedances estimated by a series R+L model indicate a resistance R=0.96 kΩ, an inductance L=80 nH and a longitudinal impedance | Z/n|eff= 0.53 Ω . The scaling law for the bunch lengthening is expressed as I0.22. The effects of insertion device in the ring on the impedance, particularly the effect of the vertical height of the in-vacuum undulator currently placed in the PLS ring is also presented.
