<p>Dr Livingstone, I presume? </p>
<p>- H.M. Stanley</p>
<p>Yesterday was maintenance day. We moved to Restricted access to facilitate the work in the hall.<br />
Engineers and technicians took the opportunty to address the issue with HMS Q2. Unfortunetely, no evident reason to the problem was found. HMS is down for the time being, meanwhile other expert sources are consulted.<br />
Florian and Lucas checked issues with some PMT (a base was found loose) and probably fADC of LAD, thus the cable was changed of channel.</p>
<p>We moved back to controlled access ~3pm and beam permit ~4, setting up SHMS. Beam recovery happened ~4:30am starting with H2 production. </p>
<p>SHIFT SUMMARIES:<br />
Swing shift -> <a href="https://logbooks.jlab.org/entry/4375380">https://logbooks.jlab.org/entry/4375380</a><br />
Owl shift -> <a href="https://logbooks.jlab.org/entry/4375576">https://logbooks.jlab.org/entry/4375576</a></p>
<p>RUN PLAN:<br />
Depending of the beam available, we will continue running on H2 until tomorrow early day shift. The plan is to move to D2 afterwards. </p>
<p>SHIFT SCHEDULE:<br />

<p>Fun Fact of the day:<br />
did you know the term SPAM, although coming from the prepared lunch meat, actually is derived from the 1970 "Spam" sketch from the Monty Python's Flying Circus?</p>
