Hi Franck,<br>
<br>
The MVT gas supply for testing in the EEL uses 10% C4H10 in argon
pre-mix gas cylinders. The gas is on order and should be delivered
in 2-3 weeks. The setup is very basic. I have attached the gas
supply P&I diagram along with the components spreadsheet. Before
this setup can be used, it must undergo pressure systems analysis by
the pressure systems design authority (DA). Once the DA has
completed his work and turns the system over to u, we can assemble
and use it.<br>
<br>
The DA for this system is Bob Miller.<br>
<br>
Thanks,<br>
George</div><div text="#000000" bgcolor="#FFFFFF"><br>

<div>Could you please remind me what the gas system for the EEL is
planned to be? I remember it's supposed to be premix bottle that
you have ordered or am I wrong? What is missing to flow gas in
the EEL?</div>

We will absolutely need the gas in the eel building
for May 29th. Indeed all the saclay team will come to
assemble the MVT and SVT on May 29th.<br>
Concerning the test I would like to run in the eel
with the forward micromegas, there is no real rush
since I have plenty of software code to develop
before. It would just be perfect to have the gas for
May 22nd if I want to do the test before the Saclay
team arrives.<br>
<br>
Cheers,<br>
<br>
Maxime<br>

<p>Greetings Maxime,</p>
<p><br>
</p>
<p>The next step is for pressure systems analysis.
The pressure systems design authority has the
test setup P&I diagram and components list.
Once the pressure systems design authority, DA
for short, completes the work, we can assemble
and use the setup.</p>
<p><br>
</p>
<p>Bob Miller, Hall B Engineer, is the DA for this
test setup. He is also the DA for the FT tracker
test setup and the full MVT gas mixing system.
Once the pressure system analysis is completed,
we can begin purchasing components.</p>
<p><br>
</p>
<p>Can you give me a time line of when you will
need the gas?<br>
</p>
<p><br>
</p>
<p>Cheers,</p>
<p>George<br>

I am a colleague of Franck SABATIE and I
arrived from Saclay 2 days ago. I would like
to discuss with you to know what remains to be
done concerning:<br>
<br>
- Gas in the eel building:If possible I would
like to run a few test with the FMT before
everybody arrives from Saclay. Moreover it is
better to have the gas ready when everybody
will arrive late May.<br>
<br>
-And also just to know what is the status of
the gas system in the Hall B. <br>
<br>
I apologize if you might have sent this
information recently to Stephan or Franck, but
I am not always in copy of the e-mails. I am
available on Tuesday, wednesday afternoon,
thursday and Friday afternoon.<br>
<br>
I wish you a nice day,<br>
<br>
Best regards,<br>
