GeFiCa

GeFiCa stands for Ge detector Field Calculator. It provides classes to calculate static electric fields and potentials in Ge detectors using various coordinates in up to three dimensions. The field potential values together with their grid coordinates are saved in a ROOT tree to take the advantage of the file compression and the Draw function provided by the ROOT TTree class. GeFiCa is provided as a shared library that can be directly loaded by ROOT. All GeFiCa classes can be used directly in a ROOT interactive session or a Jupyter notebook. Users can modify and run their calculation codes without compilation.

GEARS

GEARS is a Geant4 Example Application with Rich features yet Small footprint. The entire C++ coding is minimized down to a single file with about 550 SLOC. This is achieved mainly by utilizing Geant4 plain text geometry description, built-in UI commands (macros), and C++ inheritance. It is ideal for student training and fast implementation of small to medium-sized experiments.

MinGLE

MinGLE, a Mini Geant4 Learning Example, uses minimal C++ coding to demonstrate the usage of essential Geant4 components step by step. It is not tied to any specific experiment or third party library, which makes it a clean starting point of writing your own Geant4 applications.
