Potku, analysis software for ToF-ERDA with integrated MCERD
Potku (Finnish: kick, recoil) is an open source analysis software used for creating depth profiles from time-of-flight elastic recoil detection analysis measurement data. With the Potku 2.0 update, it now also includes MCERD for Monte-Carlo simulations of scattered and recoiled particles. The software has a graphical user interface, implemented with Python 3.10 (2023), PyQt and Matplotlib. For the analysis itself, a back-end of standalone command line programs written in C are used. Some of the analysis components can also be used independently of the GUI, if necessary.
The Accelerator Based Materials Physics group at the Accelerator Laboratory is the current maintainer and developer of the software, but Potku began its life as a student project within the Department of Mathematical Information Technology, where the user interface was developed as a part of a student software project course (2013). The Potku ToF-ERD slab-analysis code is originally written by Kai Arstila with later physics contributions from Jaakko Julin. Users are encouraged to participate in the development of the software. During the year 2018, new student project called "Monisiro" developed original Potku further. It now contains full functionality. This addition extends the possible user base of the Potku program from ToF-ERD laboratories to all laboratories having RBS or ERDA setups and even further. In the beginning on 2024 Potku 2.2.5. version achieved a major update with lots of architectural changes which also improve the user friendliness of the Potku software.
