6
Analysis? Vertex at target
TDC AO down
Z vertex in target extrapolated from positions in
A and B layers ? This controls that TDC
information is OK
7
SADC1 (output splitter?0.7) SADC2
(output splitter?0.2) For most of the signals
for the signals
of highest amplitude
A B up down up
down 0-11 0-11 0-23 0-23
A B up down up
down 0-11 0-11 0-23 0-23
We can note that B23up is noisy

Nb of SADC samples above threshold as a function
of the channel At maximum 32 samples are
registered Note Bup not always in the trigger
