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.

Turn out to be that no amplification is not good. When I look at spectrum, it does not look good.

I put the amplification to X10.

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.

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.

2) Play with gate width and HV, see how the charge changes, as we as how the 511 keV peaks shifts.

2nd Measuring of Volatage

Using Multimeter: 1.515 V

Using Scope: -72.4 mV

After battery

Before battery

Voltage: U = -72.4 mV

Impedance: R = 50 [math]\Omega[/math]

Current: [math] I = \frac{U}{R}=\frac{-72.4 mV}{50 ~\Omega} = 1.448 ~mAmp[/math]

Charge: [math] Q = I \times \Delta t = 1.448 \times 10^{-3}\Delta t ~ C[/math]

Gate timing: The GATE signal must precede the analog input by >15 ns
