Consultancy Meeting on Inter-comparison of PIGE codes (Phase II): depth profiling

The purpose of the meeting is to perform a detailed inter-comparison of PIGE data analysis codes performance in simulations of multi-layered samples with the purpose of making recommendations to the user community.

Seven exercises were defined and shared to participant code developers to investigate how the codes perform in simulations of:

• one thin film plus substrate (substrate can be heavy or light element)
• two to three films plus substrate (substrate can be heavy or light element)

with the following conditions:

• cross sections (i) varying smoothly with E and (ii) with sharp resonances – using a fictitious sharp resonance will also be considered
• (a) full beam straggling (model to be determined in exercises) and (b) Gaussian-type spread
• different film thickness (surface, deep, very deep) – to be quantified in exercises
• stopping powers from SRIM2013

Codes participating in the inter-comparison: ERYA-profiling, NDF, SIMNRA, SPACES
