1. File Name: RWM_adc_tdc.txt Description: RWM is the trigger, only taking data from RWM, measured RWM signal both from ADC and TDC.
2. File Name: RWM_PMT.txt Description: Common stop trigger comes from either PMT. Contains TDC data for the two PMTs as well as the RWM. Gives ADC data for the PMTs. the PMT U36 is in channel 1 of the TDC
and the PMT Unknown 4 is in channel 2 of the TDC. U36 is in channel 0 of the ADC and Unknown 4 is in channel 1 of the ADC.
3. File Name: Trigger_bothPMTs.txt Description: Common stop trigger comes from coincidence of both PMTs. Gives ADC and TDC data for PMTs U36 and Unknown 4. Gives TDC data for RWM signal. The PMTs and RWM correspond to the same channels as on RWM_PMT.txt.

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 added 32 more nsec delay to each PMT signal. (72 nsec total for each PMT)

Change Discriminator threshold from -210mV to -300mV (as measured by the probe, there is a 10-1 scale, so this is really 30 mV threshold)

0-4-V in Discriminator channel 0, threshold -299.6mV
1-4-V in Discriminator channel 1, threshold -298.2mV
0-5-V in Discriminator channel 2, threshold -299.9mV

6. File Name: VW_00020_0001_4PMT_RAW_1512170000.txt change the delay to 1.1 micro sec

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.
