| + | Re-setup data acquisition system. The signal delay was not long enough, some signals were not totally included int the gate. So, I delayed signal even longer, and made gate wider. Now, whenever there is a trigger, all the signal is included. However, if I trig on the signal on the scope, I see that there were not trig for all the signal. In other words, we are missing some signals. | ||
| + | |||
| + | Is this a discriminator problem? | ||
| + | |||
| + | It was misplacement of the source. I accidentally dropped the source. | ||

| + | |||
| + | To differentiate my pedestal with signal: | ||
| + | |||
| + | 1. Run a while with my gate missing my signal (by delaying gate so that gate misses signal). | ||
| + | |||
| + | 2. Pause the run, record event number when paused (Np). Record pause time. | ||
| + | |||
| + | 3. Continue the run and finish it. | ||
| + | |||
| + | 4. Plot the events in the root. First plot with events from 1st event to Np. Then plot the events after Np. | ||

| + | Charge changing as pulse width changes | ||
| + | |||
| + | T F:You are just measuring noise if the signal size has a mean of less than 100 channels. | ||

| + | S S:Looks like the channel 16 is not good. I also changed the polarity. It worked. | ||

Detector and Parts
Big pulse due to scope 1 M ohm scope resistance
Pulses in the following to detectors are huge due to we used wrong scope resistance of 1 M ohm.
IAC NAI_1
Without Mu material:
HV = 700 V
With Mu material:
HV = 700 V
IAC_NAI_2
With Mu material
HV = 700 V
Tests with 50 Ohm Scope Resistance
All the following tests are done under 700 V.

ROC was dead. I think it is because I amplified the signal from dynode by 20 times, the trigger is too frequent for daq to handle.
I lowered the amplification to X1, which is no amplification.

More test on Det2
Re-setup data acquisition system. The signal delay was not long enough, some signals were not totally included int the gate. So, I delayed signal even longer, and made gate wider. Now, whenever there is a trigger, all the signal is included. However, if I trig on the signal on the scope, I see that there were not trig for all the signal. In other words, we are missing some signals.
Is this a discriminator problem?
It was misplacement of the source. I accidentally dropped the source. Source was on the top of one of the Pb brick around detector.

HV vs 511 Shift for Det3
Third Na22 peak test Using Detector 3
There were third peak after 1.27 MeV of Na22. This is third peak is the coincidence of 0.511 MeV and 1.27 Mev peaks, according to its position.
We would like to study this peak and its ratio to the 1.27 MeV peak.

Pedestal Subtraction
We need to pedestal subtraction. Here are the commands to plot in root with event number.
root [4] ntuple->Draw("ADC3:EventNumber");
root [6] ntuple->Draw("ADC3:EventNumber","ADC3<100");
root [8] ntuple->Draw("ADC3:EventNumber","EventNumber<1000");
root [9] ntuple->Draw("ADC3:EventNumber","EventNumber<1000 && ADC3< 500");
root [12] ntuple->Draw("ADC3","EventNumber<4000 && ADC3< 100");
To differentiate my pedestal with signal:
1. Run a while with my gate missing my signal (by delaying gate so that gate misses signal).
2. Pause the run, record event number when paused (Np). Record pause time.
3. Continue the run and finish it.
4. Plot the events in the root. First plot with events from 1st event to Np. Then plot the events after Np.

Put the Na22 and Co60 peaks together
Charge of single pulse of 511 peak
1) Confirm ADC charge calibration by using a battery. Integrate gate with around 50 ns.
2) Play with gate width and HV, see how the charge changes, as we as how the 511 keV peaks shifts.
3) Charge vs ADC_Channel number, should be linear. y intercept is noise.
4) HV vs Charge for 511 keV for each NaI detectors.
Confirming ADC Charge Calibration
Voltage of battery: V = 1.556 V
Changing Pulse widths
Charge changing as pulse width changes
T F:You are just measuring noise if the signal size has a mean of less than 100 channels.
S S:Looks like the channel 16 is not good. I also changed the polarity. It worked.
But the change is not linear with the pulse width.
