<div>I sent this to George earlier. There is a lot to do on the
system. I can give you more detail as to why that is but I
will be working on it this weekend to completely reassemble
it. Where is the system now?</div>

<div>Hi George,</div>
<br>
<div>Making a May 1st deadline is possible but will require
some extra work from me. As far as a path forward there
are still several issues:</div>
<ul>
<li> There are still mixed materials. This does not
conform to the specifications listed in the Swagelok
catalogs/manuals and has to be corrected.</li>
<li> The system components were not properly assembled.</li>
<li> There are components from different manufactures
connected together (Parker/Swagelok). <span

</ul>
<div>I am working on a list of components from Swagelok etc.
that will have to be obtained (purchased or otherwise). It
is not too extensive but the target group does not stock
1" swagelok components so I will have to "find" or
purchase them. After the components are obtained the
entire system will have to be disassembled and reassembled
correctly to bring it into compliance.</div>
<br>
<div>Post assembly there is still the following work to be
completed:</div>
<ul>
<li>examinations of all mechanical joints and materials<br>
</li>
<li>proper filing of all documentation related to the
system</li>
<li>Inspection of the system including final system
walkdown</li>
<li>Testing of the system including a final leak test.</li>
<li>Registration of the pressure vessel and relief device</li>
<li>System turnover to Bob Miller (assumed owner of the
system)</li>
</ul>
<div>The DSG can certainly help assemble the system under
the supervision of a trained (as determined by the system
DA) technician. They can also help with setup of the
pressure test(s). Everything else will fall onto the DA
and examiner with the final walk down of the system
performed by the JLAB QA inspector.</div>
<br>
<div>I have CC'd Patrizia because she asked a similar
question of me this morning and I wanted to make clear
what needs to be completed.</div>

<div>Hi Dave,<br>
<br>
We have due date on the RICH air cooling system according
the my supervisor, 1 May is the day they will start using
it in the EEL for testing. <br>
<br>
I have some ideas, but you said you had a plan involving
the pre-swage tool. Can we meet and decide a way forward
on this?<br>

<div>Hello Valery,<br>
</div>
<br>
<div>This morning we received the RICH
electronic boards. The boxes are in EEL
121 small cleanroom's gowning area. What
would be the timeline for testing and
installing the electronics?\<br>
</div>
<br>
<div>Also, when would the air cooling system
be needed? A rough date is needed to give
Dave Meekins, RICH gas system Design
Authority, adequate time to approve the
gas system since it is a pressure system.
We cannot operate the air cooling system
without DA approval.<br>

<div>Please let us know.<br>
