<p>Hi Carlos,</p>
<p>I will install a full bottle of premix tomorrow and train the
Jack Segal to change the bottles during the shut down.</p>
<p>When the experiment stops tomorrow, please reduce the premix flow
to 50 ccm.</p>
<p>Regards,</p>
<p>Bob<br>

<p>In order to prepare for the shut down, and as was
agreed in the morning Hall B meeting, we plan to run
pre-mix gas a very low flow, with two bottles. But one
of then is totally empty. Sebastian swap the bottle with
the new one (it is at 1700 psi). </p>
<p>Deuterium is running low, BUT maybe we can run until
the end of the production (tomorrow).</p>
