expect five days of beam
</li>
<li> the nights and weekends plan is dead
</li>
</ul>
</li>

exit made
</li>
</ul>

</li>
<li> will implement time-of-flight and start counter
trigger
</li>
</ul>
<br>
<span class="mw-headline" id="DAQ.2C_Sergey_F.">DAQ, Sergey
F.</span><br>
<ul>

<li> attempt made a mode 7 running, get to 80% live
</li>
<li> bottleneck appears to be event builder
</li>
</ul>
<br>
<span class="mw-headline" id="FDC.2C_Lubomir">FDC, Lubomir</span><br>
