While helping with the MPS work last night I found The fibers on Rack 2B10 are either mislabeled or plugged in wrongly, #9 finer is in #7 connector, #7 fiber is in connector#8. Is this part of the issue?</div>

<div class="">Started shift finishing up a few items left on MPS checkout, this took longer than expected & consumed the day shift. Swing shift had gun HVPS MPS interlock problem, this was fixed and then is was discovered that the Drive Laser Pulse Controller
(DLPC) was not “talking” with the MPS (there are 8 fiber optic cables, when all are active CW is allowed, each one has a lower beam power limit). System expert was not able to come in to fix problem last night so it will be addressed first thing this AM. </div>
<div class="">Pulsed mode operations began to find remaining problems. There were also a couple viewer/camera issues that need repair. Beam threading to 1X will continue this morning.</div>
