<p>Hi Guys, <br>
</p>
<p><br>
</p>
<p> I have spoken with MCC about the concern with leave the
magnets at any current in restricted access. They have agreed to
go to controlled access when we are ready to ramp magnets and stay
there. They will be fully staffed at the time and have no problem
switching to controlled. Eugene will be on site assisting Probir
with the sweep and has agreed to call for controlled access at the
onset of ramping the magnets.</p>

We intend to run the magnets as soon as we come back from

working around the magnet (if this is not adm. controlled that
we have seen and experienced in the past).</div>

Please let me know. Then we can plan every thing upon our return
