Hi Sean,<br>
<br>
the tagger microscope walk correction does not work for the
CPP/NPP run (RunPeriod2022-05).<br>
attached you can see two examples of tagger microscope column 19
where on the vertical<br>
axis is the tagger time (with all corrections) minus the RF time
and on the horizontal axis<br>
is the signal amplitude.<br>
As you can see the amplitudes in the CPP/NPP run are much smaller.
I guess that is why<br>
the walk correction does not work for the counter.<br>
It's pretty much the same for all counters. All amplitudes are way
smaller. I guess it needs a<br>
dedicated walk correction calibration.<br>
<br>
cheers,<br>
Beni<br>
