The eleventh International Serpent User Group Meeting was hosted by Forschungsneutronenquelle Heinz Maier-Leibnitz (FRM II), TUM, in Garching, Germany, from August 29 to September 1. The meeting was organized as a hybrid live/on-line event. More than 20 participants joined the meeting in Garching, with varying number of on-line participation. The technical programme included a half-day workshop on VTT's new Kraken computational framework.

The Serpent developer team wants to thank all participants for interesting presentations and discussion, and TUM for organizing and hosting the event.
