Spring EPICS collaboration meeting 2026

20 avr. 2026, 07:15 → 24 avr. 2026, 18:00 Europe/Paris

Amphithéâtre Alain Aspect - 1G58 (ENS Paris-Saclay (Ecole Normale Supérieure, Université Paris Saclay))

The Experimental Physics and Industrial Control System, EPICS, is a set of Open-Source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as particle accelerators, telescopes, experiment beam lines and other large scientific experiments. The EPICS Collaboration Meetings provides an opportunity for developers and managers from the various EPICS sites to come together and discuss their work and inform future plans. Attendees can see what is being done at other laboratories, and review plans for new tools or enhancements to existing tools to maximize their effectiveness to the whole community and avoid duplication of effort.

The Spring 2026 EPICS Collaboration Meeting and related workshops will be held Monday April 20 to Friday April 24, 2026 at Paris Saclay University .  The Collaboration Meeting uses three days: Monday - Wednesday, April 20-22, 2026. Workgroup meetings and training sessions will be held on Thursday and Friday morning, April 23-24, 2026.

A visit to some CEA Saclay installations is planned for Friday afternoon.

Thank you for joining us this spring in Paris, France!

10:00 → 11:00 EPICS Meeting Talks: Status Reports

10:00 EPICS legacy at CEA Saclay

This presentation will give an overview of the use of EPICS, its tools and hardware platforms in our laboratory for particle accelerator projects over the last 30 years. We joined the EPICS community in 1993 for the control system of the Tesla Test Facility at DESY, a collaborative project for which EPICS was being advised. Subsequently, our Institute was involved in 2 experiments at the Jefferson Laboratory, for which EPICS was also chosen.
For the Spiral2 project at Ganil EPICS was selected in 2007. In these different projects EPICS was running on a VME/vxWorks platform associated with ADAS acquisition boards.
Between 2014 and 2017, we used EPICS solutions based on VME and Linux and IOxOS boards essentially for test stands for the ESS and Saraf collaboration projects.
In 2017, we decided to migrate to MTCA.4, Linux associated with IOxOS boards for the new projects. This MTCA platform will be presented as well as our evolution in EPICS.

10:40 Upgrading an Operational EPICS Control System to EPICS 7

The EPICS based control system at SNS has been in operation since 2006. After 20 years of running EPICS Version 3, we have embarked on the journey of upgrading to EPICS 7. This upgrade is necessary as support for EPICS 3 is discontinued and to take advantage of new features especially more advanced data handling capabilities. Most importantly, Secure EPICS will only be available for EPICS 7 systems and this is a critical piece to meet increasing cybersecurity mandates. However, having a large, mature operational EPICS control system in a complex machine operating over 5000 hours per year means changes must be implemented in phases with minimal disruption to operations and availability. This talk will discuss our strategy and progress towards upgrading to EPICS 7.
