keyword=multiple hits, T3
I confirmed that the multiple hits exist in raw data for
trigger 3. They appear in ADCs and TDCs, which means at
the INPUT to the MLU. Perhaps (and this is just a guess), some
of this enhancement is due to cosmics which are a significant
fraction of the 70 Hz and are notoriously dirty. (Run 1938, around
the time of the complaint.) It would be easy to eliminate
with timing cuts. The trigger ignores the dirt, just needs a track.
