Experimental Verification and Analysis of Beam Loading Effect Based on Precise Bunch-by-Bunch 3d Position Measurement (remote contribution) | |
|

| Beam loading effect is one of the main bottlenecks of synchrotron radiation light source to further improve performance. The theoretical analysis and numerical simulation of beam loading effect had been done very well, but the corresponding diagnostics tools relatively poor, usually only streak camera is used to observe the synchronous phase distribution and the intensity distribution in bunch train. SSRF developed precise bunch-by-bunch 3D beam position measurement system. Equipped with this system not only steady-state beam parameters (filling pattern, synchronous phase, bunch lifetime), can be accurately measured and recorded, but also transient stage data can be perfectly captured and recorded. Therefore, the beam loading effect can be more comprehensive and accurate experimental verification and analysis. In this paper, the measurement results of synchronous phase, synchronous tune, synchronous oscillation damping time and other parameters with and without third harmonic cavity are introduced and discussed. | ||
