Reference Figure 1. Operation status of the SPring-8 storage ring at around 9:30 a.m., January 30, 2004.
One sees that the stored current shown by the blue color in the figure is recovered from 75 mA to 100 mA by the scheduled beam injection (10 p.m. and 10 a.m.). The current decays from 100 mA to 75 mA during the interval between the beam injections (12 hours). The light green line represents the beam lifetime.
