</li>
<li> Sascha
<ul>
<li> last week cosmics taken
<ul>
<li> new ROCCDC1 did not work, reverted firmware to
old version</li>
<li> ran BCAL cosmic trigger</li>
</ul>
</li>
<li> working on new firmware for DIRC SSP
<ul>
<li> firmware like Hall B RICH</li>
<li> having library compatibility problems</li>
<li> trying to unify libraries with Ben Raydo</li>
<li> trigger SSP needs modification</li>
</ul>
</li>
<li> ready to start the run</li>
<li> DIRC: special crate, optical connection there
<ul>
<li> lacks SSP read-out</li>
<li> LED system going in, CAEN 1495 used to drive
LEDs</li>
<li> will be ready for run</li>
</ul>
</li>
<li> CompCal
<ul>
<li> 10 FADCs in crate, connected to read-out</li>
<li> Needs connection to trigger system, Ben will do
that after finishing DIRC</li>
<li> CAEN 1495, LED system installed</li>
</ul>
</li>
</ul>
</li>
<li> Sergey
<ul>
