IBA DataFurnace is a general­‐purpose analytical code for data analysis of ion beam analysis (IBA) data. It is in active development with the first version released in 1997. It is general within its specifications, and was developed as a general analysis tool for IBA of any type of sample. Its main features are: implementation of the largest array of techniques of any IBA code; implementation of the most advanced physics and algorithms available; simultaneous data analysis of any combination of spectra collected from a given sample.
