<p class="MsoNormal">We just discussed this at the engineering meeting. The plan outlined by your point 3 is the way to go. You can do all the preparation for turn on work starting July 13 and leave the last step of ramping magnets up until the beamline work
is complete. We don’t see any interference with other work in the hall. Important thing is maintain social distancing at all times and coordinated your work with Denny. Also keep track of you work in the logbook.<o:p></o:p></p>

<span style="font-size:12.0pt">Start on 17th (Friday) means we will finish up on 23rd (Thursday) - 17, 20, 21, 22, 23 (5 days as scheduled) - this leaves us with 1 day float (24th Friday).<o:p></o:p></span></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">

<span style="font-size:12.0pt">Therefore was suggested earlier to start on 13th and get prepared. This will leave the magnet to be energized for a later date (thinking at least both magnets at full field for at least a day before physics start, Denny can do
that and expect some one to be at site to switch-on the MPS and the magnets reaches full field).<o:p></o:p></span></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
<span style="font-size:12.0pt">The point 3 is important as i see, because HALL is also expected to be at full field and cryo cross-talk may interfere and run the magnets down or trip. This we want to mitigate earlier than 27th and keep physics running.<o:p></o:p></span></li></ol>
