(Eugene)</span></h2>
<ul>
<li> If really needed, staff can access the campus, for
example, to retrieve medication from one's office. Contact
Eugene who will in turn contact Rolf Ent for approval.</li>
<li> Hall walk-throughs are being conducted as per plan. Tim
reported that the walkers are making daily log entries.</li>
<li> The Lab's stay-at-home policy for non-essential
personnel has been extended to the end of April.</li>
<li> Governor Northam has just issued a <a rel="nofollow"

href="https://www.governor.virginia.gov/media/governorvirginiagov/executive-actions/EO-55-Temporary-Stay-at-Home-Order-Due-to-Novel-Coronavirus-(COVID-19).pdf">stay-at-home
order</a> for the state of Virginia. Tim ran down the
details.</li>
<li> The Lab is thinking of running again this calendar year
in the event that plans for the CHL shutdown are seriously
affected. For Hall D, that might mean picking up where we
left off a week ago and executing the last six weeks of
the run.</li>
<li> Budget: the President's budget calls for a 15% cut.</li>

<ul>
<li> Beni: we need to stay out of each others way,
prioritize use</li>
<li> Mark D: Analysis coordinator should prioritize</li>
<li> Mark I: Should be discussed at Production and Analysis
meeting since calibrations, reconstruction, and physics
analysis all involved
<ul>
<li> priorities could be enforced by
favoring/dis-favoring accounts in the batch system,
allows non-priority tasks avoid a complete halt</li>
