This is the homepage of the main Hall A physics analysis software, "Podd". The software is an object-oriented, highly modular and extensible framework built on top of ROOT. Classes are available for the most common analysis tasks involving data from the standard Hall A experimental equipment, in particular the HRS spectrometers and detectors. Standard physics calculations for single arm (e,e'), conincidence (e,e'X) and photoproduction reactions are available, as well as for auxiliary tasks such as energy loss corrections, vertex position calculations, etc.

The included Software Development Kit (SDK) provides users with a rapid development environment for building experiment-specific extension libraries. One can quickly implement new detectors, physics computation modules and even entire spectrometers.

Minimum System Requirements

  • Platforms
    • Linux with gcc 4
    • macOS 10.6 with Xcode command line tools.
    • Other Unix-like platforms that support ROOT should work with minimal changes
