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.

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

IAC NaI Det1 Scope 1.png

With Mu material:

HV = 700 V

IAC NaI Det1 Scope 2.png


IAC_NAI_2

With Mu material

HV = 700 V

IAC NaI Det2 Scope 1.png

Tests with 50 Ohm Scope Resistance

All the following tests are done under 700 V.

Starting CODA

Starting

Do it at 7 different terminal.

Need to do command on all of them:

Then Run control interface appears.


1. Press "Connect"

2. Press "Configure" (on the top middle)

Then "Run Type Configuration" appears

3. Select "SIS3610", Press "OK"

4. Press "Configure" again.

5. Select "V792_ADC", Press "OK"

6 Press "Download"

Second Attempt to Start CODA

msqld

telnet roc1

et_start

rcServer

coda_eb

coda_er

runcontrol

Run Control Interface

1. connect

2. Configure

3. Select V792_ADC

4. at "REad From" select "roc1"

5. Configure

6. Download


Then stopped.



Dr. Forest looked all the terminals and said all of them are resdponding except roc1

He restarted roc1, Then followings are what he had done

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.

 you need to do gaussian fits, then calibrate to determine how mannel channels per keV, then apply the calibration
so the x-axis is in keV and redo the gaussian fits so we can see the mean and widths for resolution.

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

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.
