    keyword=S0 check

    I took the opportunity of the controlled access to look at S0 signal again, both signals looks similar with still a small reflection about 150 ns after the pulse. I tried to see if the BNC cable was well seated on both S0 PMT, they were. But I did not have time to check after the discriminator since Heidi and Mark were done. The discriminator channel or the TDC channel might be a bit noisy but if we cut on the right timimg peak the ADC spectrum looks clean. I will try to move to another TDC/discriminator channel at next pass change.
