We will likely run again starting in early April for five
weeks. There is a chance that beam
may come to the Hall as early as early March. The plan is to
have the detector ready
for running by the beginning of March.

<br>
<span class="mw-headline" id="Calibration">Calibration</span><br>
<br>
Sasha is working on time-walk corrections to reduce the
number of parameters for the
channel-by-channel calibrations.
<br>
<br>
<span class="mw-headline" id="FADC_Voltage_Range">FADC
Voltage Range</span><br>
<br>
From Sasha's talk at the Run Coordination meeting last year,
we see that there are a
substantial number of overflows in the FADC data. We
discussed whether it was better
to reduce the PMT voltage to get more pulses into range. The
downside there is that we
may give up timing resolution. On the other hand lower
voltage will extend the lifetime
of the PMTs. In the end we decided to ask Fernando to
increase the range from 1 V to 2
V. Fernando has already solicited work lists from the group;
we will be coming a bit late
to the process.

<span class="mw-headline" id="Equipment_Loan">Equipment Loan</span><br>
<br>
The extension of the loan of equipment from JLab to FSU
(Loan TJNAF#44283) has received all approvals.
The loan runs for a year.

<span class="mw-headline"
id="Tasks_to_Prepare_for_the_Next_Run">Tasks to Prepare
for the Next Run</span><br>
<br>
We identified several basic tasks/procedures that either did
not get done or were not
developed to completion, including a discriminator threshold
scan and a procedure for
gain equalization. We agreed to come prepared with a list to
discuss at the next
meeting.

<br>
FSU will nominate a speaker for the upcoming meeting.

<span class="mw-headline" id="Next_Meeting">Next Meeting</span><br>
<br>
We agreed to meet again in a week. It looks like weekly
meetings might be appropriate
between now and the next run.
