<div>All, </div>
<div><br>
</div>
<div>In the RF meeting yesterday there was much productive discussion. I think we are firming up what is needed for System Recovery and full powered tests. It would be nice if we have have some folks from Engineering (Kimber/ Mounts/ Bagget, others welcome
too), to continue to discuss what is needed and ensure we are all on the same page. Steve, Mike, Mike Merz, and myself sat down this morning and populated the SAD calendar with some milestone dates, and beam ops days starting next week. Please have a look
at it. Attached is our latest schedule, it will be updated after the BTeam meeting, and sent back out possibly tomorrow. </div>
<div><br>
</div>
<div>Another thing that we need to nail down for 5 pass spin up is the sequence for beam to 2R, before full ORFP. Do we go our normal route, or take the opportunity before going to 2R to do the drift through the SL and into Hall A to get an energy/ polarization
measurement at first pass to Hall A as Mike Tiefenback suggests??? Is it possible given possible shunt regulation issues? What are pros of cons in taking this route before 5 pass spin up? If we get numbers for corrections/ calibrations what do we do with them?
I haven't seen the ATLis for this route? Tief/ Yves/ Jay who is writing this ATLis? </div>
<div><br>
</div>
<div>I would like to comment on other minutes from last week as well, if there are corrections or updates to my comments please say so. </div>
