This is the first beam test with the original electronics (phase detector), the precision mover (including the interferometer sensor), well established alignment and the focusing optics. We did the BPM calibration by moving the center BPM in 316nm steps while tracking the beam orbit by the other BPMs. The BPM resolution was estimated to be 72nm.

The properties of the beam jitter was also measured. The position jitter at an optical waist point and the angle jitter was measured to be 540nm and 2.6μrad, respectively.
