<p>Thank you very much. I guess the MFC was working well with N2. <br>
</p>
<p>It is planned that we will have good beam until tuesday. So the
priority will be for the data taking. If any test needs to stop
flushing premix in the detector, it will have to wait for
wednesday (So far good beam has been very rare and just arrived
last night.)</p>
<p>Kind regards,</p>

<div>I will be sending the spare mfc to the Hall B Gas tech,
Todd Ewing, later today for installation. I'll have to
periodically stop the controls during the swap (briefly), so
you may see some alarms on HTCC flow, pressure, and moisture.
The system will probably have to be stopped at least twice for
short periods of time.<br>
