<p>Code for TOF Hit factory has been updated. The default time
window for matching ADC and TDC hits has been increased from 10 to
20ns to match the output signal width of the discriminators. The
code was modified to NOT overwrite already
found matches with new TDC match but instead make new Hit.

<h3><span class="mw-headline" id="PMT_testing">PMT testing</span></h3>
<p>The new HV power supply sent to FSU already stopped working. Us
single channel module for now.
Gain measured for 10 PMTs. The measured gains differ from the
factory values by +/- 10-20% this is more than previously seen.
One PMT seems to have very low QE.
