We contued to work on aerogel and lucite detectors.
The lucite gain matching is done except two channels showed short 100 ns
delay. It seems that two channels have no cable delay at the panel behind the SOS
hut. Thus, the signals are ahead of the ADC gate.
The aerogel threshold studies were done. We took pion runs with 0.424, 0.53, and
0.63 GeV/c to cross the aerogel threshold. Each run had more than 2.5 M triggers
(250K pions).
Openned hall at 7:45 am for target work.
