Online Bunch Length Monitoring for Storage Ring using a Fast Photodiode | |
|
||
| Providing bunch lengths and a filling pattern of the bunch train in real-time is one of the important challenges in beam instrumentation of the 3rd generation light source. In particular, the time length and intensity information of the synchrotron light is useful to beamlines and their users who perform time-resolved experiments. We developed an online monitoring system that can measure bunch lengths and a filling pattern simultaneously by directly observing the synchrotron radiation with a picosecond-resolution photodiode and high input-analog-bandwidth digitizer. A Gaussian deconvolution method to restore the original waveform of synchrotron radiation using the system impulse response function was developed and adopted. In this paper, we present the experimental setup, signal processing method, and several machine study results in detail using the fast photodiode in the PLS-II | ||
