The LEGO model of the ALICE experiment at CERN was designed by both high school and university students in Germany as part of a workshop series organised jointly by Christian Klein-Boesing, Marcus Mikorski and Sascha Mehlhase for and funded by the ErUM-FSP T01 “Expansion of ALICE at the LHC: experiments with the ALICE detector at CERN” and KONTAKT projects, in turn funded by the German Federal Ministry of Education and Research (BMBF).

The workshops started back in January 2021 and after more than 100 hours of preparation during more or less weekly meetings, on the weekend around 26 June the first two models were built at the University of Münster and Goethe-University Frankfurt.

Construction manual

Of course there’s also a construction manual …

Please find the overview document in PDF format here.

The complete set of instructions for all individual model parts and the general assembly can be downloaded as a ZIP archive (compressed version with non-functional links).
The instructions also contain parts/sorting lists and dependencies for each component and the ZIP archives also Studio IO model files of the detector(s).


The model was designed and for the first time built as part of a workshop organised jointly by Christian Klein-Boesing, Marcus Mikorski and Sascha Mehlhase. Most of the actual design of both the detector model and the construction manual was done by the following team (credits and copyright lies them) …
