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...

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...

At CEA/IRFU, we design and provide particle accelerators along with their control systems. A key part of these systems is the Machine Protection System (MPS). Specifically, the SBCT (system for beam current transmission monitoring) monitors the beam using ACCT sensors. To ensure machine protection, this system must be able to stop the beam in only a few µsec if an anomaly is detected.
The...

Caputlog is a runtime logging tool that streams events through Logstash and stores them in Elasticsearch, while PVInfo provides a React-based visualization layer for PV metadata. This project integrates Caputlog logs with PVInfo to deliver context-rich diagnostics, improved traceability, and actionable analytics. We engineered a modular data pipeline that ingests caput events from Caputlog,...

The EPICS ecosystem continues to grow in capability, but several software engineering practices that have become standard in the broader open-source world remain unevenly adopted across the EPICS community. This talk is about closing that gap - and making the ecosystem a better place to build and contribute together.

The CEA Paris-Saclay Irfu is responsible for most of the EPICS control system for the Saraf Linac accelerator. This scope includes the control and the tuning of the beam, the machine protection system (MPS) and the timing system (TMG).
The machine protection system prevents any damage in the accelerator by shutting down the beam in case of detection of risky incidents like interceptive...

The CSNS accelerator beam-synchronous data acquisition (BSA) system is designed to ensure immediate data availability and capable of providing a comprehensive view of the entire machine through high sampling rates and precise timestamping data. The BSA data can be used for machine tuning, troubleshooting, and early fault prediction. EPICS 7 structured PVs are employed to integrate raw waveform...

For decades, Diamond Light Source (DLS) and other facilities have been reliant on GUI packages that were first developed in the 90s and 2000s (e.g. edm, medm). CS-Studio was an attempt to move away from this, but wasn't very popular at DLS because of its sluggish performance and dependencies on Eclipse RCP and SWT.

One of the capabilities of CS-Studio / Phoebus is to load HMIs from a web-server. It is shown how this capability can be used to dynamically-generate HMIs and embedded display elements. This may be used to customize HMIs for users.
By reacting to search broadcasts, PVs may also be dynamically-generated on a per user (or other) basis. The methods that can be used to achieve this are...

Large EPICS installations often operate hundreds of soft IOCs distributed across multiple hosts. Managing these IOCs consistently—covering application creation, startup and shutdown, monitoring, validation, and upgrades—can become increasingly complex and error-prone as systems grow and standards evolve.
