<p><strong>23:10</strong></p> <p>Beam set to bunched mode to observe beam lifetime. </p> <p>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</p> <p>This corresponds to ~13.5 keV in the beam energy.</p> <p>Attachment 1 shows target scan. Maximum still observed at a horizontal beam position of 1.0 mm.</p> <p>Moving 0.5 V up or down does not impact the orbit enough to shift the beam position off the target.</p> <p>Beam lifetime off target seems larger than previous, perhaps better vacuum conditions?</p> <p>Back to coasting beam</p>
