# Programs
|
|
|
|
### convertPixie.sh
|
|
|
|
convert NSCL-evt (raw data) to pixie-evt, ripe off the NSCL header.
|
|
|
|
### convertRoot.sh
|
|
|
|
convert pixie-evt to root with event building and mapping.h applied.
|
|
|
|
### mapping.h
|
|
|
|
Thsi define the mapping
|
|
|
|
### peachCake.C/h
|
|
|
|
Analysis class from TSelector. It do the primary analysis and apply corrections. It has option to output a new root file (with prefix "zzz_") with tree branches:
|
|
|
|
- eventID | eventID
|
|
- runID | runID
|
|
- AoQ | A/Q value of PID
|
|
- Z | Z value of PID
|
|
- crossTime | cross scint. T2 analog time
|
|
- crossEnergy | croos scint. T2 analog energy
|
|
- flag | event identification flag, +1 = has Beta, +2 = has Ions, +4 = has Beam
|
|
- vetoFlag | veto, +1 = has Front trigger, +2 = has Rear trigger, +4 = has cross scint T2/B2
|
|
- xIons | x-pos of Ions
|
|
- yIons | y-pos of Ions
|
|
- xBeta | x-pos of beta
|
|
- yBeta | y-pos of beta
|
|
- dyIonsTime | dinode Ions time
|
|
- dyBetaTime | dinode Beta time
|
|
- veto_f | front veto detector energy
|
|
- veto_r | rear veto detector energy
|
|
|
|
### DecayFinder.C/h
|
|
|
|
The DecayFinder.C/h analysis the zzz_XXX files to obtain the decay curve for various isotopes.
|
|
|
|
### PIDCutCreator.C and PIDCutChecker.C
|
|
|
|
Create/Check the PID cut.
|
|
|
|
### scipt.C
|
|
|
|
root macro to run analysis flow at once.
|
|
|
|
# Analysis Flow
|
|
|
|
|
|
|
|
1. The NSCL-evt file to pixie-evt file (nscl2pixie)
|
|
2. Use the EventBuilder to build event and apply the mapping.h
|
|
3. Use peachCake.C/h to analysis and output a new root file.
|
|
4. Use DecayFinder.C/h to obtain the decay histogram.

|
### DataBlock.h
|
|
This defines a class **DataBlock** to store data from pixie digitizer
|
|
|
|
### nsclEvtReader.h
|
|
|
|
This defines a class **NSCLEvtReader** to read NSCL evt file.
|
|
|
|
### nscl2pixie
|
|
|
|
This is a program to convert NSCL-evt file to evt file. Basically ripe out all NSCL header.
|
|
|
|
The bash script **converPixie.sh** use this program to batch convert NSCL-evt to evt file.
|
|
|
|
### evtReader.h
|
|
|
|
This defines a class **evtReader** to read pixie evt file.
|
|
|
|
### EventBuilder
|
|
|
|
This is a program to convert pixie-evt to root file with event building. This program will apply the mapping.h. The output tree has branches
|
|
|
|
1. evtID | event ID, unsigned int
|
|
2. multi | event multiplicity, int
|
|
3. detID | detector ID defined in mapping.h, int
|
|
4. e | energy, double
|
|
5. e_t | timestamp, ULong64_t
|
|
6. cfd | fine time from cfd, int
|
|
7. qdc | 8-section of intergrated trace, int[8]
|
|
8. multiClover | multiplicity of Clover
|
|
9. multiBeam | multiplicity of beam-line detector
|
|
10. runID | runID, e.g. run-0330-17 = 330*100 + 17 = 33017
