<ul>
<li> Appraisals will be initiated today. They are due by
Oct. 14.
<ul>
<li> With uncertainty due to the upcoming continuing
resolution Physics had decided no promotions for now
</li>
</ul>
</li>
<li> 12 GeV budget: project is done
<ul>
<li> all construction accounts close
</li>
<li> one exception is account for pre-ops
</li>

FADCs wrong, Sergey P. is fixing
</li>
</ul>

</li>
<li> failed at 400 Hz
</li>
</ul>
</li>
<li> finalizing read-out list for all detectors
</li>
<li> want set-ups to be able to run with triggers and
crates
</li>

</li>
<li> timing issues in combining BCAL and FCAL
</li>
</ul>
</li>
<li> next area of work: pair spectrometer

<li> trigger through GTP, course counters only
</li>
</ul>
</li>
<li> Eugene: can specific crates be excluded from read-out
based in trigger type?
<ul>
<li> S: in principle yes, not implemented
</li>
</ul>
</li>
<li> Vladimir Berdnikov has seen PS signals, looked at
SiPM noise for each bias group
<ul>

</li>
</ul>
</li>
</ul>
<h1> <span class="mw-headline" id="Fernando">Fernando</span></h1>

<ul>
<li> rack moved on upstream platform
</li>
</ul>
</li>
<li> cables are all settled except for long-term network
switch
<ul>

</li>
</ul>
</li>
<li> Eugene: we plan to remove the tagger system on Friday
</li>
</ul>
<h1> <span class="mw-headline" id="Yi">Yi</span></h1>
<ul>
<li> solenoid
<ul>
<li> power supply
<ul>
<li> 2 spare controller boards came in
</li>
<li> 1 repaired
</li>
<li> makes 4 total
</li>
</ul>
</li>
<li> slew rate slower than that set
<ul>
<li> suspicion: either connect of board or fault
in daughter board
</li>
<li> will order a spare daughter board
</li>
<li> can do a test at low current
</li>
<li> should not impede operations
</li>
</ul>
</li>
<li> Eugene: helium in magnet for a month now
</li>
<li> Jonathan Creel adjusted parameters on JT valves,
smoother operation now
</li>
<li> Eugene: flow controller for leads on the way
</li>
</ul>

</li>
<li> need self-trigger
<ul>
<li> start counter trigger not a priority
</li>
<li> yet start counter trigger useful for cosmic
testing of many other detector subsystem e. g.,
CDC, BCAL (radial track path enhancement), FDC
(in coincidence with TOF to give horizontal
cosmics) and may be useful for beam data as well
