Beam set to bunched mode to observe beam lifetime. 

Electron cooler voltage setpoint kept at 246.8 V. Note this is 0.5 V lower than the previous test where the setpoint was 247.3 V

This corresponds to ~13.5 keV in the beam energy.

Attachment 1 shows target scan. Maximum still observed at a horizontal beam position of 1.0 mm.

Moving 0.5 V up or down does not impact the orbit enough to shift the beam position off the target.

Beam lifetime off target seems larger than previous, perhaps better vacuum conditions?
