Presentation

The G E T library defines classes to process signals from the G E T electronics architecture. It is designed to analyse data from real measurements (that fill the G E T system channels output samples) or from simulations (that must be considered as the input channels data that are processed by the G E T system library objects).

The purpose of processing simulated data is mainly to test the analysis procedures developed for physics analysis, and to some extend to set the optimal experimental conditions.

Requirements, compilation and configuration

For compilation see page GET libraries compilation and OS environment. Only Linux OS are supported.

Using the libraries

Linking the library to C++ codes
Loading the library in a ROOT session
Additional tools associated to the library:
- GETActarEventReader analysis

Library description

The C++ source files are organised in source subdirectories:

Core : the classes describing G E T system main objects, following the G E T electronics architecture
Processing : the classes needed for signal processing (response functions and filtering classes).
Config : the classes holding G E T system configuration data (from XML configuration files)

For more details, see:

Core classes architecture for the description of the G E T objects that define a system;
Signal processing classes for the processes that may be defined for signal processing;
GET configuration files for interaction of the core objects with experimental system configuration files (not yet implemented);
Examples for use of the GET library for examples of the use of the library.

There are also ROOT macros provided for display or analysis of the G E T signals. A specific documentation is generated at compilation time, for the description of the ROOT macros provided.
See file http://www.cenbg.in2p3.fr/AnalyseActar/GET5.0/root/html/index.html (website documentation)

Units system

G E T core classes:

time unit = us (this can be important if mixing the library objects with other packages (such as Geant4).
