<div class="moz-cite-prefix">Dear George, dear Stephan,<br>
yesterday we had a meeting with Bob and Eugene to plan the FT
installation in Hall-B.<br>
We were told that, while in teh hall, we will ONLY use mixed gas
(not premixed bottles).<br>
This is not consistent with what you mentioned. If this is the
case, we do not need any bottles since the plan is to move the FT
to the Hall at the beginning of July with no further tests in the
EEL.<br>
Thanks in advance for clarifying it<br>
Cheers<br>
Marco<br>

remember that 4 of those pre-mix cylinders in the EEL gas

<pre>The MVT gas usage is greater than was originally estimated. This brings up the question, do we need to buy more pre-mixed gas to complete testing? If we do need to order more pre-mix 10% C4H10 in argon, it should be done ASAP due to the long lead time of 4-6 weeks.<o:p></o:p></pre>
