Description

The 6-20 phase probes (PPs) are installed in the all cyclotrons of RIBF for non-destructive measurement of their isochronism. We have measured isochronism by observing the zero-cross points of bunch signals from PPs using an oscilloscope for nearly 20 years. We have developed new measuring system of isochronism using a lock-in amplifier for commissionings of 3 new cyclotrons started at 2006. In order to investigate the consistency of those two measuring methods of isochronism, we measured the isochronism using an oscilloscope and lock-in amplifier simultaneously. Additionally, we have performed Fourier analysis to bunch signals observed using an oscilloscope to investigate the difference of beam phases between frequency components. (author)
