Last night a tropical storm passed through the area, spawning tornadoes. A tornado warning
<div>caused a general shutdown of the lab, which will take an estimated 12 to 24 hours to recover from.
</div>
<div>I'm pretty sure there was no damage or injury, we just have to recover many systems that were</div>
<div>shutdown. How this affects our schedule, I don't know yet. I'm working on finding out. But I
</div>
<div>have cancelled shifts until Thursday Day shift. </div>

<div>News in hall A:</div>
<div><br>
</div>
<div>* Leaks in Ar/CO2 for R-HRS GEMS. The GEMS themselves are leak-tight. Chuck Long is
</div>
<div>chasing the leak, with Jack and Chandan right behind.</div>
<div><br>
</div>
<div>* Magnets: I gather the problems are not insurmountable but take time; see Jack's halog 3820186</div>

<div>* L-HRS: detectors look pretty good, Devi, Bogdan, and Albert working hard.</div>

<div>* R-HRS: detectors. It would be good if we could <u>certify what we can</u> (DAQ/trigger/scalers/scintillators).</div>
<div>However, the VDCs has a problem: connections to the 5V for amplifiers and the thresholds.</div>
<div>Ethan, Jack, and Bogdan are working on this problem. Devi will certify what we can when we can.</div>
<div><br>
</div>
<div>* Parity DAQ: thorough tests being done by Cameron. They swapped an ADC on L-HRS that</div>
<div>had a bad / flakey pedestal, so I think that solves the problem Devi pointed out yesterday.</div>
