Experimenting with getting more of the pulses into the integration window for the ADC, we tried adding to paddle 0-4-v and extra 32 nsec delay (ADC 0). If we are happy with the results, we will likely repeat this for the other 3 paddles

We have determined that with 0.5 nsec resolution the largest 12 bit time allowed is 2047.5 nsec. This is not enough for a delay lager than 2 micro sec. We are going to talk to Geoff about changing the resolution to 8 nsec. So we will have 32  micro sec.
