| MOP030 | Developments of 4GSR BPM Electronics | 87 |
|
||
| The emittance of the 4th-generation storage ring (4GSR) to be constructed in Cheongju-Ochang, Korea, is expected to be approximately 100 times smaller than the existing 3rd-generation storage ring. With the decrease in emittance, more precise beam stabilization is required. To meet this requirement, the resolution of the beam position monitor (BPM) system also needs to be further improved. We have conducted research and development on the electronics of the BPM system for the 4GSR storage ring. In order to perform fast orbit feedback in the 4GSR storage ring, we need to acquire turn-by-turn beam position data, with a desired beam position resolution of 1 ¿m. Additionally, prototypes of the bunch-by-bunch monitoring system are being developed for the transverse feedback system and longitudinal feedback system. The internally developed electronics are intended to be modified for future use as monitors for multi-bunch beam energy measurements at the end of the linear accelerator, by adjusting the logic accordingly. In this presentation, we will describe more details of the current status of the development of the beam position monitor electronics for the 4GSR in Korea. | ||

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 | ||
