γ-ray tracking algorithms: a comparison

In the context of the development of a new multi-detector for γ-ray spectroscopy such as AGATA, we discuss the performances of 2 different γ-ray tracking algorithms: back-tracking and forward-tracking. The same Monte Carlo simulated data is used to compare the capacity of each algorithm to reconstruct the trajectories of a given number of photons emitted into a 4π germanium shell.
