The inaugural International Workshop for Ion Source Technicians (IWIST) took place from 1 -3 April 2025 at the ISIS Neutron and Muon Source. Hosted by the ISIS Low Energy Beams Group of the Accelerator Beams Division at ISIS, the event was designed specifically for hands-on professionals working with ion sources in particle accelerator environments.
This first event brought together technicians, engineers and specialists from leading international laboratories, reflecting the truly global relevance and interest in building a dedicated community of ion source professionals. Over three days, participants shared experiences from the front line of operations, discussed troubleshooting strategies and explored best practices for maintenance – all in a collaborative, technician-focused setting.
What set IWIST 2025 apart was its informal, practical and discussion-led format, which fostered open exchange, peer support and real-world learning. Sessions covered a wide range of topics, including ion source builds and refurbishment, run-ups, radiofrequency (RF) and vacuum systems, equipment obsolescence, safety protocols and integrating R&D into daily operations. Knowledge retention and best working practices were also key themes.
A variety of ion source types were discussed, such as H⁻ Penning ion sources and RF ion sources, highlighting the diverse technologies and approaches used across international facilities. Attendees were encouraged to speak candidly about both challenges and innovations, creating a dynamic environment where learning flowed in all directions.
Beyond the technical exchange, the workshop strengthened the international community of ion source professionals, highlighting shared goals and common challenges. As one participant reflected, “It’s rare to be in a room where everyone truly understands the day-to-day challenges of this work – IWIST has given us that space.”
IWIST directly supported all four pillars of the UKRI Technician Commitment: visibility, recognition, career development and sustainability. Its success demonstrates the value of targeted technician-led initiatives and highlights the potential for similar approaches to be adopted across other technical areas within ISIS.
With overwhelmingly positive feedback and strong interest in future workshops, IWIST has established itself as a vital platform for technician development, cross-laboratory collaboration and continuous improvement in ion source operations.
