  KEKB was upgraded from 2011 over 5 years in order to increase the luminosity and started SuperKEKB commissioning in 2018 after the test operation. In order to cope with large beam currents and small beam sizes, various updates have been applied to the beam instrumentation system. This talk summarizes the performance of beam instrumentation in SuperKEKB Phase-III and challenges to it.

  For the accelerator-based future of high energy physics at the energy frontier, CERN started to investigate a 92 km circumference Future Circular Collider (FCC), as e+/e collider the FCC-ee will operate at beam energies up to 182.5 GeV. Beside the machine operational aspects, beam instrumentation will play a key role in verifying and optimizing the machine to achieve the ambitious beam parameters and quality. This paper gives a brief overview of the various challenges to develop the required beam instruments, with focus on beam position, beam size and bunch length measurements, and well as an outline of the planned R&D activities.
