Hi Marc,</div>

For the testing this month, I would like to use the MFC308 to supply the drift chamber. The chamber is currently not set up to run at 1050 mbar, so I will just use a bubbler to control the pressure.</div>

As soon as they are done testing, we can change over to the new control system and test it while the detector is bypassed.</div>

<p class="x_x_MsoNormal">The Alicat MFCs have arrived. Brian has started developing LabVIEW drivers for them. I have started writing the ALERT gas controls software to run in the EEL building.</p>
