Introduction

This is the analysis package for the SOLARIS DAQ. It is supposed to be the analysis path for the SOLARIS DAQ.

The folder struture is

Analysis
├── README.md
├── SetupNewExp // bash script to create new branch and raw data folder
├── SOLARIS.sh // bash script to define some env variable and functions
├── Armory // analysis codes, independent from experiment.
├── Cleopatra // Swaper for DWBA code Ptolomey and simulation
├── data_raw // should be the symbolic link to the raw data, created by SetUpNewExp
├── root_data // symbolic link to converted root file, created by SetUpNewExp
└── working // working directory, depends on experiment.

ROOT issue

We are still using TProof for parallel calculation. TProof is not pre-compiled since 6.32+. And 6.30 only precompiled for Ubuntu 22.04. So, for system using Ubuntu 24.04, user must precompiled to root in order to work.

Analysis & Simulation

The Armory/AnalysisLib.h constains many small but handy functions.

All class headers are started with Class*.h

The classes DetGeo** and ReactionConfig are fundamental for loading the detectorGeo.txt and reactionConfig.txt.

Both txt file support empty lines, and up to 2 settings. The reason for that is for dual-array configuration. It has potentail to extend and include more settings. But it is two now, one for upstream array (reaction) and downstream array (reaction).

The TransferReaction class is only use one of the reaction from the reactionConfig.txt.

  TransferReaction::SetReactionFromFile("reactionConfig.txt", ID); // ID = 0 or 1

Same for the Helios class

  HELIOS::SetDetectorGeometry("detectorGeo.txt", ID); // ID = 0 or 1

Event Builder

The EventBuilder is at the armory. It depends on the Hit.h and SolReader.h.

Hit.h

The Hit class stores a hit (or a data block)

SolReader.h

The SolReader class read the sol file. It can be loaded in CERN ROOT alone.
