- Turning coffee into code – GATE 10 Hackathon 2026
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 …Read more “Turning coffee into code – GATE 10 Hackathon 2026”

We are happy to share our latest work:Probing arbitrary polarized photon pairs undergoing double Compton scatterings by a dedicated MC simulator validated with experimental data. Polarization correlations in two-photon systems are fundamental to our understanding of quantum mechanics. However, for high-energy photons (beyond the optical regime), measurement remains challenging, only partial information can be obtained through Compton scattering techniques. Monte Carlo simulations offer a powerful way to explore these processes, modeling both photon production and the effects that distort the observed signals. Together with our colleagues from … - Data Generation for Machine Learning Classification of Coincidence Events for Siemens Biograph Vision Quadra PET
