Description
We report on the latest measurement results from the visible light synchrotron radiation monitor (SRM) during high current operation at SuperKEKB. Beam measurements covering both steady state conditions and rapid transient phenomena—specifically "final-turn" measurements—revealed an increase in vertical beam size immediately before the beam was aborted during sudden beam loss (SBL) events. Subsequent measurements in the HER and LER rings identified differences in the phenomena observed between the two rings. While the optical system's high dynamic range enabled precise measurement of beam halo profiles over a wide range, we present measurement results for the LER following the implementation of SBL countermeasures and compare them with before countermeasure data.
