After posting a run plan for a busy weekend with beam (see HALOG <a href="https://logbooks.jlab.org/entry/3439805" class="">3439805</a>), there was a serious vacuum event near the RF separator yesterday afternoon (see HALOGs <a href="https://logbooks.jlab.org/entry/3439842" class="">3439842</a> and <a href="https://logbooks.jlab.org/entry/3439890" class="">3439890</a>). After speaking with the crew chief this morning, I cancelled the day shifts today (except for target operator).</div><div class=""><br class=""></div><div class="">I was told that if the vacuum group can find and fix the leak today then we could still see beam on swing. On the other hand, until they find the leak, we won't really know how much trouble we're in (or not). </div><div class=""><br class=""></div><div class="">So keep your fingers crossed. I'll uncross mine from time to time to update you on the situation as it unfolds.</div><div class=""><br class=""></div><div class="">Greg (HallA RC)</div><div class=""><br class=""><div class="">
