At the beginning of February, 2026, Wojciech Krzemień participated in the GATE 10 Hackathon held at the Holland Proton Therapy Center in Delft. The event gathered 27 participants from 10 countries working on the development of the GATE simulation toolkit.
During the hackathon, the positronium source model was successfully transferred from GATE 9 to GATE 10. This implementation enables simulation of multiple decay channels with configurable activities and branching ratios, supporting realistic modeling of positronium decays.
The meeting was also an excellent opportunity to collaborate in person with the IMPET project’s scientific partner, David Sarrut.
We would like to thank the organizers for the excellent event, and especially Nils Krah for creating a productive and inspiring atmosphere.
