Longitudinal Parameter Measurement System Based on Time-Frequency Domain Joint Analysis | |
|
||
| This paper proposes a novel technique for measuring longitudinal bunch length by performing spectral analysis on the beam signals to extract the bunch length information for each bunch and each turn. A high-speed oscilloscope is used to capture original button signal with more than 7000 turns information and an offline Python script is used to retrieve bunch length and phase information. A streak camera is used to calibrate the transfer function of the acquisition system. Experiments were carried out at the Shanghai Synchrotron Radiation Facility and the Hefei Light Source by capturing the electrode signals with an oscilloscope during single bunch injection and harmonic cavity tuning in the storage ring. The calibrated longitudinal bunch length measurement system yielded favorable results, with a larger dynamic range and higher time resolution compared to the streak camera. In the future, the system has the potential to be transplanted into a processor to achieve online longitudinal beam measurement for each bunch. | ||
