<br>
Starting Monday we will begin functionality test to verify the spare<br>
works as a normal mfc. Then we will swap it in, to observe the behavior,<br>
on the system with Argon and with C4H10. We have manpower to do the<br>
testing, we may suggest some changes to the valve panel, for instance an<br>
isolation valve on the flow side of the mass flow controllers would help<br>
with some of the troubleshooting. Hall B has assigned Todd Ewing as the<br>
MVT system technician.<br>
<br>
For the current run you have two bottles of premix on hand, and 10 more<br>
on the way, this will give us time to get the mixing system tested and<br>
running.<br>
<br>
Thanks,<br>
<br>
Marc<br>
