We are pleased to announce RL4AA'26, the fourth workshop of the series organised by the Reinforcement Learning for Autonomous Accelerators (RL4AA) Collaboration. After three very successful workshops (KIT in 2023, Salzburg in 2024, and DESY in 2025) RL4AA'26 will be hosted as a LIV.INNO Workshop on Reinforcement Learning for Autonomous Accelerators by the University of Liverpool and Cockcroft Institute in the musically iconic port city of Liverpool.

RL4AA brings together the reinforcement learning and accelerator physics communities to share results, practical insights from the field, and the big questions ahead for real-world RL. Expect engaging keynotes, invited and contributed talks, a lively poster session, and a hands-on coding challenge.

More details:

Please join us if you have worked in reinforcement learning or you are simply interested and would like to start! This workshop is intended to foster discussions and to start interesting projects together.

We highly encourage every participant to submit a poster and share their work with other participants to have a lively exchange!

Do not hesitate to share this invitation with your colleagues and contact the organizers through ansantam@liverpool.ac.uk for questions.

We can’t wait to welcome you to Liverpool in 2026!
