Marcin Kulbaka - homepage

Content of this site.

Hello. I have decided to create homepage and publish my "mini - projects". The main goal is hosting of Liebmann project, which is still under development. I publish new versions of program and documentation. I correct errors and try to add few words, so the project could be more understoodable. The homepage has been developed since 2024. It is minimalistic (static HTML) and it does not gather data (except hosting provider).

Project Liebmann

• Liebmann - (still unfinished) software to make calculations in field of charged particle optics.
• Liebmann - Polish version.
• Liebmann - Slovak version (short introduction).
