The commissioning of the PF storage ring started at 2:49 PM.

After tuning the beam transport line, the injection magnets and the betatron tunes, the beam was circulated over 4 turns at 10:23 PM.

Single-pass beam orbit in the first stage.

Positions of the injected beams were measured using a single-pass beam position monitor. The beam was circulated over more than 4 turns. Upper to lower graphs: raw signals from button electrodes, sum of the BPM signals, horizontl and vertical beam positions. The beam positions at 16 locations of the ring were measured during four turns.
