Description

The online bunch-by-bunch position and phase monitor has been established by employing a high-speed analog-to-digital converter, meticulously synchronized with the accelerator's radio frequency. I/Q demodulation is utilized in the phase monitor to calculate the beam phase. To unravel the intricacies of bunch motion, independent component analysis has been employed, efficiently segregating the bunch motion into discrete sources. The resulting bunch motion is a direct outcome of the linear combination of these distinct sources, significantly simplifying the overarching data analysis procedure. An examination of the tune variation in these sources is conducted through a numerical analysis of fundamental frequencies. These monitors are used to study the bunch motion during injection, transient beam loading effects at various beam currents, and synchronous motion during routine operation.
