Still using pulser triggered from protons. 12 microsecond delay from protons to gamma-flash + 1.75 microsecond delay from gamma flash to pulser. 20 mV pulser output into 50 ohm impedance (10 mV final output) of both polarities (using two pulsers, one NE pulser and one BNC PB5 pulser). Changed pulser setting to run with 5 microsecond delay for approx. 1 hour, then change to 10 microsecond delay.
