Thus, a large fraction of our effort has been concentrated on reducing and managing beam losses. To validate the beam loss optimizations, residual radiation measurement along the ring provide us with further information. By relating signals of the beam loss monitors with the measured distribution of the residual radiation, achievements of the high power beam operation will be described. In this presentation, we will report on the measurement results of residual radiation distribution along the ring together with the relation with the beam loss signals.
