<ul>
<li> If you want access to any of the buildings at the Lab
during the shutdown, please contact Eugene and have him
put your name on the list.
</li>
<li> Congress has approved a budget, president's budget
plus 1 M$
<ul>
<li> the Fall run will be for accelerator
</li>
<li> before 12 GeV, must install cooling in tunnel,
dogleg upgrades
</li>
<li> Spring run for us will be two months or less
</li>
</ul>
</li>
</ul>
<br>
<span class="mw-headline" id="David">David</span><br>
<ul>
<li> event size for mode-8 4 to 4.5 times greater than for
mode-7, mode-7 4 times greater than original estimate
</li>
<li> EPICS to ET not working
</li>
<li> want to put F1 TDC configuration parameters in data
stream
</li>
</ul>
<br>
<span class="mw-headline" id="Sergey_F.">Sergey F.</span><br>
<ul>
<li> looking for bottleneck in read-out rate
</li>
<li> within crate, mode-7 or 8, no difference in rate
</li>
<li> live-time low, 70% live
</li>
<li> multi-block not tried
</li>
<li> event size: calorimeter noise, FDC big contributors
</li>
</ul>
<br>
<span class="mw-headline" id="Alexandre">Alexandre</span><br>
<ul>
<li> need to buy radiation monitors before the next run
</li>
</ul>
<br>
<span class="mw-headline" id="Sergey_P.">Sergey P.</span><br>
<ul>
<li> assembling new trigger test set-up
</li>
<li> 1 crate so far
</li>
<li> will re-activate F117 set-up
</li>
</ul>
<br>
<span class="mw-headline" id="Sascha">Sascha</span><br>
<ul>
<li> playing with different trigger types
</li>
<li> calorimeter in coincidence with start counter
</li>
<li> with coincidence FCAL rate down by 10
</li>
<li> able to lower threshold on FCAL from 1500 to 1200
</li>
<li> tuning delays on GTP
</li>
<li> trigger identity recorded by TS
</li>
<li> took some data with ST, TOF, FCAL coincidence with
different TOF requirements
</li>
<li> took ST and TOF trigger for calibrating minimum
ionizing peak
</li>
<li> last Sat., hodoscope gains adjusted with pair
spectrometer trigger
</li>
<li> TDC hits seen in pair spectrometer, hodoscope, and
microscope
</li>
<li> PS trigger can be added now
</li>
</ul>
<br>
<span class="mw-headline" id="Tim">Tim</span><br>
<ul>
<li> tomorrow shielding changes, VESDA work
</li>
<li> Jan. Feb. work list being worked up, basic list in
place
</li>
<li> helium will stay in magnet
</li>
<li> beamline drawings are out
</li>
<li> FDC chiller: want to ship our for repair
</li>
</ul>
<br>
<span class="mw-headline" id="Mark_I.">Mark I.</span><br>
<ul>
<li> starting to generate simulated data for data
challenge 3
</li>
<li> software review in Feb: Hall D will focus on topics
related to offline handling of data taken this run
</li>
</ul>
<br>
<span class="mw-headline" id="Simon">Simon</span><br>
<ul>
<li> TDCs, ADCs: studying timing consistency
</li>
<li> issues with TOF matching to charged tracks
</li>
<li> measured TOF speed-of-light about 14 to 16 cm/ns
</li>
<li> matching charged tracks to start counter has
inefficiencies
</li>
<li> matching start counter times with tagger a challenge
at present
</li>
</ul>
<br>
<span class="mw-headline" id="Lubomir">Lubomir</span><br>
<ul>
<li> Luke Robinson has been awarded a DOE Fellowship. He
will start here in March, will be here for a year
</li>
<li> FDC reconstruction has good starting time now, from
start counter
</li>
<li> plotting drift times
</li>
<li> recover same resolution as in EEL cosmic data
</li>
</ul>
<br>
<span class="mw-headline" id="Yi">Yi</span><br>
<ul>
<li> will be leaving JLab for an opportunity near Chicago,
starts end of January...sad news for Hall D
</li>
<li> solenoid in stable state with connectors re-seated
and ice ball gone
</li>
<li> Rodrigo Mendez will test MCPMTs from Argonne; there
has been progress in their fabrication
</li>
</ul>
<br>
<span class="mw-headline" id="Mark_D.">Mark D.</span><br>
<ul>
<li> BCAL reconstruction work: low-level objects first
calibration
</li>
<li> analyzing recent tests
</li>
<li> working on overall calibration scheme
</li>
</ul>
