<p><strong>Day Shift</strong> (<a href="https://logbooks.jlab.org/entry/4125403">https://logbooks.jlab.org/entry/4125403</a>):</p><p>No beam due to ongoing MCC issues. Lack of even a short term plan for beam delivery and impact on the whiteboard schedule, including late-notice cancellation of Tuesday's RF recovery day. Once we were aware of this, we opted to change back to polarized ND3, work that was almost derailed by a water leak in the solenoid power supply (<a href="https://logbooks.jlab.org/entry/4125657">https://logbooks.jlab.org/entry/4125657</a>)</p><p> </p><p><strong>Swing Shift</strong> (<a href="https://logbooks.jlab.org/entry/4125603">https://logbooks.jlab.org/entry/4125603</a>):</p><p>No beam for entire shift.

MCC have problems degaussing tagger due to an IOC problem, but this is eventually resolved and raster is re-established (<a href="https://logbooks.jlab.org/entry/4125955">https://logbooks.jlab.org/entry/4125955</a>)</p><p> </p><p><strong>Short Term Plan</strong>: Continue production running on negatively polarized ND3.

The wafers are wrapped in distinctive red and gold coloured foil. Dark chocolate wafers, wrapped blue and gold, are also available. Over seven million caramel wafers are made and sold every week, a fact written on the wrapper of every bar, and more than the number of people living in Scotland.</p> </div>
