ERYA-Bulk and ERYA-Profiling: An application for quantitative PIGE analysis

The applications entitled ERYA-Bulk and ERYA-Profiling (ERYA stands for Emitted Radiation Yield Analysis) are two programs which implement PIGE (Particle Induction Gamma-Ray Emission) analysis of samples which can be either homogeneous (handled by ERYA-Bulk) or heterogeneous (with multiple layers, which are simulated by ERYA-Profiling).

The homogeneous model uses an analytical method to evaluate the nuclear yield as function of the mass fraction of the element(s) of interest. A routine is available to fit the experimental yields in order to compute the correct sample atomic composition.

Otherwise, the heterogeneous model takes consideration of the physics with greater detail, including straggling in the energy lost by the projectiles, making a more realistic yield simulation, whose level of accuracy the user can control in exchange of computational time.

Here, we present the latest developments of these codes, which include new features, functionalities and direct handling of different source files. ERYA-Bulk and ERYA-Profiling are currently compiled and tested for Linux, Windows and Mac OS X operating systems.
