</li>
<li> Accelerator, SAD work continues
<ul>
<li> refurbishment and installation of cryomodules</li>
</ul>
</li>
<li> computer center: farm empty
<ul>

</li>
<li> Medcon: no news
<ul>
<li> e.g., mask policy for unvaxed worker still being
worked out</li>
</ul>
</li>
<li> property validation: please complete yours</li>
<li> Theory sponsoring one day workshops to develop input to
the long-range plan</li>
<li> New staff positions: two open, one opened mid-December,
the other a few days ago
<ul>
<li> panel will get application packets at end of month</li>
<li> BZ: what skill will be emphasized? EC: data
analysis first, also role in software support</li>
<li> ad written to cover broad range of skills</li>
<li> input of the group to desiderata solicited</li>
<li> upcoming hardware projects: calorimeter, GEM</li>
</ul>
</li>
</ul>
<h2><span class="mw-headline"
id="Theory_Workshops.2C_Patrizia">Theory Workshops,
Patrizia</span></h2>
<ul>
<li> meant to develop ideas for an energy upgrade to
contribute to long-range plan</li>
<li> should be done by summer</li>
<li> 1 or 2 pages on each topic</li>
<li> EC: similar white paper was produced last year. PR:
these will address higher energy in particular</li>
</ul>
<h2><span class="mw-headline" id="Work_in_the_Hall.2C_Tim">Work
in the Hall, Tim</span></h2>
<ul>
<li> CPP hardware installed
<ul>
<li> got gas system working yesterday</li>
<li> flushed with Ar-CO<sub>2</sub> for 30 hours</li>
<li> ready for cabling, but waiting on them</li>
<li> target assembly getting installed</li>
<li> waiting for crates from CDC, they are being used
for cosmic tests</li>
</ul>
</li>
<li> FDC chiller repaired</li>
<li> heat exchanger for target compressor flushed</li>
<li> chiller for FCAL2 to be certified soon</li>
<li> Bobby Bunton and Chris Allen helping with FCAL2
assembly</li>
</ul>
<h2><span class="mw-headline"
id="FCAL_Module_Construction.2C_Sascha">FCAL Module
Construction, Sascha</span></h2>
<ul>
<li> 146 modules fabricated</li>
<li> lot of time spent preparing parts, pre-assembly</li>
<li> Detector Support Group helping with pre-shaping foils
and wrapping crystals</li>
<li> Olga from GWU visited
<ul>
<li> GWU will involve students</li>
<li> measured PMT diameters</li>
<li> will set-up fabrication of silicon cookies at GWU</li>
<li> waiting on loan agreement for vacuum pump</li>
</ul>
</li>
<li> goal: 30 modules per week</li>
<li> Igal cutting Kapton and Tedlar</li>
<li> New base electronics prototype received from Fernando
<ul>
<li> PCBs and parts should be ready by end of summer</li>
<li> would like test on CompCal during the summer</li>
<li> uses less power than previous design</li>
<li> mechanical issues with supplying power: meeting
tomorrow on this</li>
</ul>
</li>
<li> crystal procurement situation described at
collaboration meeting</li>
<li> plan to move to EEL in April or May</li>
</ul>
<h2><span class="mw-headline" id="KLF_Project.2C_Eugene">KLF
Project, Eugene</span></h2>
<ul>
<li> decision to use Hall C design for compact photon source
<ul>
<li> reduce planned power on target by factor of two</li>
</ul>
</li>
<li> discussions on-going on how to mount magnet for flux
normalization of K<sub>L</sub>s
<ul>
<li> funding for designer running low</li>
</ul>
</li>
<li> next FY will require more capital funding for KLF
materials</li>
</ul>
<h2><span class="mw-headline" id="Run_Documentation.2C_Simon">Run
Documentation, Simon</span></h2>
<ul>
<li> propose combination of documentation for CPP and PrimEx</li>
<li> CPP 27 nA might be too low for accelerator to sustain
reliably</li>
<li> AD: every two days running at 100 nA needed to track
machine energy</li>
</ul>
<h2><span class="mw-headline" id="On-Call_Phones.2C_Mark_D.">On-Call
Phones, Mark D.</span></h2>
<ul>
<li> RC and slow controls phones will be replaced with
iPhones</li>
<li> others will remain as they are</li>
<li> HE: possible change in provider in near future, might
require wholesale replacement of phones</li>
<li> AA: we could do a test to make sure all phones are
working</li>
