<p>Beni reported that Sascha Somov has not had a chance to
test the trigger yet.

<h3><span class="mw-headline" id="CAEN_TDC">CAEN TDC</span></h3>
<p>Beni installed our spare CAEN TDC into the TOF crate for
the downstream scintillator paddles used by CPP. When his
standalone read-out program failed, he found that the
firmware needed upgrade. He contacted Greg Kibilko to get a
copy of the new firmware and Sergey Furletov downloaded it
to the TDC yesterday. He is now taking data to adjust the
least-count-equalizing resistors. After that he wants to do
a integral non-linearity calibration on the board.
</p>
<p>Paul asked Sasha O. to check the version of the firmware on
the CAEN TDC they have at FSU. During CPP, with the JLab
spare in the Hall, the FSU unit is the designated spare.

<p>Beni will review the section on walk corrections. There
have been several iterations of the method over the years.
