Most APS beamlines are using VME crates as a major part of their control system.
The VME hardware is expensive and becoming obsolete, with replacements for many of the above items no longer available. The VxWorks software is also expensive.Prior to the shutdown for APS-U April 2023 the 4 GSECARS beamlines at sector 13 were using an EPICS system based primarily on 7 VME crates running...

This talk will present some exploration of ideas about how the oac-tree sequencer by ITER could be integrated in the surrounding EPICS infrastructure. Topics like implementing reactive sequences, modularizing the trees and utilizing templating to configure reusable modules will be covered.

The Karlsruhe Research Accelerator (KARA) at KIT uses a customized software layer to “activate” EPICS alarms based on the operating state of the accelerator. Since KARA does not run 24/7 and also operates in very different modes, the basic idea is to be able to temporarily disable or enable some EPICS alarms based on certain conditions. To date, we have used our own Java software layer for...

At NSLS-II, EPICS applications for the accelerator and beamlines reside on dedicated VLANs that are isolated for security and network bandwidth. Because clients must run their applications within their respective networks, this poses a challenge for enabling centralized observability and control for facility staff with various roles. We have created a single portal to access EPICS process...

AreaDetector developers started holding a series of remote collaboration meetings back in February 2024 with the main goals of discussing and addressing pull requests (PRs), defining collaboration policies and procedures for areaDetector repositories, and deciding on administrative matters when required. This initiative increased the volume of discussions and reviews of proposed changes in the...

Epics normative types allow exchanging information consistently based on data models, which -- according to our experience -- simplifies establishing processing chains.
Based on our personal experience we suggest to look at these processing chains using the triple: "aggregate, transform, modify". We think that is useful to add aggregation (or enrichment) or modification of data models as...

Most EPICS Collaboration meetings have a talk from someone in the Core Developers Group which follows this formula: List some recent releases of EPICS and describe the major changes that were included in the latest; introduce some exciting new features that have been merged into the development branch since that last release; outline some functionality that's still being developed or is under...

Abstract

In this presentation, we will describe the design, implementation, and integration of a modular EPICS-based control architecture for the Timepix3 detector ecosystem deployed at ORNL neutron and X-ray facilities. Our control framework leverages multiple interlinked components:
1. ADTimePix3 Detector Driver: Built upon the EPICS areaDetector framework, the ADTimePix3 driver offers... -

EPICS was developed as a toolkit for implementing scientific control solutions. It is designed and implemented to provide a robust and high performance set of tools that can be used to limit the need for software development. This presentation will revisit these fundamentals as they relate to the current state of EPICS.

The Archiver Appliance at the APS accelerator records, stores, and manages process variable data to support operations and machine studies. This talk provides an overview of the deployment, including the process variables monitored, CPU and memory usage, storage rates, and hardware setup. We describe how sampling specifications (rate and method) are determined based on process variable type,...

We introduce a native Phoebus client for orchestrating Bluesky experiments via the Queue Server. The client supports viewing/editing the plan queue, submitting validated plans, starting/pausing/stopping execution, opening/closing the run-engine environment, and monitoring status—all from within Phoebus.

We present a new Phoebus data source that speaks directly to PVWS (PV Web Socket) endpoints, enabling low-latency, firewall-friendly access to EPICS Process Variables. PVWS bridges Channel Access and PVAccess to WebSockets and transmits values plus metadata (units, limits, severity, timestamps), sending full metadata once and then only deltas—reducing bandwidth. Integrating this datasource in...

The Phoebus 5.X releases build on the existing framework by expanding the functionality of core modules and services, introducing new user-facing applications, and updating the technology stack to improve scalability, security, and long-term maintainability. The collaboration has also continued to broaden, with contributions from additional facilities, supporting Phoebus’s role as a...

The distributed architecture of MRF timing systems provides a fitting platform for implementing interlock functions with low latency. In the Fast Beam Interlock (FBI) system developed for Nusano, input statuses from Event Receivers (EVRs) are transmitted to the Event Master (EVM), combined into logical flags and propagated to EVR outputs.

At SNS we have developed a new nameserver that builds the PV cache dynamically by searching for PVs on the network and storing them until IOCs are alive, without the need to pre-load or keeps a database of PVs. This project was started to support the specifics of the highly diverse EPICS environment with many flavors of Channel Access clients/servers. The PVmapper was implemented to allow...

A dynamic simulation model of the Central Helium Liquefier (CHL) at the Spallation Neutron Source (SNS) has been developed using the EcosimPro commercial software. This model facilitates production system replication providing virtual environments for software testing, operator training, process analysis and troubleshooting. In this integration project, the EcosimPro model will be deployed as...

The VM is available in different Linux flavors, with a scripted and reproducible build. Instances can be easily updated from GitHub, allowing per-event configuration and interesting off-label applications. -
Guilherme Rodrigues de Lima20/09/2025, 16:05
The SIRIUS accelerators have used containers for IOCs for years, but build definitions and launch scripts were often duplicated, and image sizes could be over 3GB. On the other hand, the SIRIUS beamlines, until recently, used IOCs installed in a shared NFS, which complicated application management, especially across different OS versions.
To address these issues, we have developed a...

The proposed OPC UA server for EPICS pvAccess will enable EPICS-based systems to connect to a variety of external frameworks and tools. It will facilitate communication with not only SCADA frameworks but also any system with an OPC UA client, including HMIs, Remote Handling systems, and Virtual Reality tools, among others.
