Oportunistic Beam studies
Trigger Setup
1.) The V895 was double pulsing and its output pulse maxed out at 40 ns
|
| The V895 "Maj" output is shown on Ch1 along with the NaI signal which was discriminated by it |
2.) inserted a gate delay generator to change the V895 output pulse to a microsecond
|
| I took the "MAJ" output and used a Phillips Gate Generator to extend the pulse length in order to stop multiple triggers |
Pre-Beam DAT test runs
| Run# | run mode | Run length (sec) | Beam | Target | Trig Logic | VME discriminator Threshold (mV) | HV1 (setting/V) A1 | HV2 (setting/V) A3 | PL (setting/ns) | PTW (setting/ns) |

| 4084 | sample | sec | e+(0.150 na) | Chromox | (Det1 AND Det2) | 50 | 2.2/0.888 | 3.0/1.2 | Changed discriminator to 50 mv for both channels it was at 20 the scalers will count differently now but the trigger theshold is still the same 100 mV | |

| 4086 | sample | sec | e+(0.05 na) | Chromox | (Det1 AND Det2) | 50 | 2.2/0.888 | 3.0/1.2 |
- stop using V895 and used a discriminator (Phillips 708 set to ~100 mV) and logic unit (phillips 758)
Scope pict traces for TEK0020 -> TEK00
Ch1(Yellow)=Majority
Ch2(Blue)=Beam SYNC
Ch3(Pink)=Annih. Det. #1
Ch4(Green)=Annih. Det. #2
Data Analysis
Replay
running the decoder using the personal account on the opsmdaq0 failed; perhaps due to problems writing its output to the /data disk
to convert a data file into a rood file I needed to login to opsdaq0 under the username "idaq"
then execute the following command
/work1/fanchini/decoder/fadc_decode_Source /data/annihilation/Annihilation_Sample_4086.dat
This created the summary text file and root file for run 4086
MakeClass
Load up the ntuple and click over to the "T" tree
Then onthe command line type
T->MakeClass();
