In recent years, the construction of European Spallation Source, including the control system, has progressed very rapidly and we are operating a substantial number of IOCs in production. Our goal from early on has been to apply comprehensively the new emerging features of EPICS; accordingly the talk will cover the status of our use of EPICS 7. Our underlying system architecture, in particular...
Apart from moving from Debian to RHEL as a baseline operating system, the NSLS-II facility has embraced a plethora of new powerful automation and orchestration tools. Changes to how we manage our systems have brought along new considerations and approaches in the areas of EPICS software packaging, distribution, IOC code management, and deployment. The talk covers updates in these areas, and...

Armstrong Test Facility (ATF, formerly Plum Brook Station) is a 6,400 acre (26 km^2) research campus in Sandusky, Ohio that operates a number of unique world-class test facilities which are used by NASA, other governmental agencies, and the private sector to conduct full service facility and test system preparation for complex and innovative research and flight programs. The...
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.
I am leading an effort at sector 13 to completely eliminate the 7 VME systems during the dark year.
I plan to install the following to...
Detectors based on TimePix3 chips are complementary to existing image-based detectors. In addition to the 2D image, the TimePix3 chip allows the collection of time information of each hit down to the nanosecond level. The timing capabilities allow new possibilities in particle and photon data collection, by providing not only characterization of accelerator source but also science related to...
I will present the RFSoC based 500 MHz BxB Beam Position Monitor development status and epics control system interface.
The RFSoC-based advanced BxB provides many capabilities for measuring BxB beam transients, multi-bunch coupling, bunch charging, and beam trip transients.

I will introduce BxB...
In order to increase data acquisition rates and to lower complexity at the embedded level, Fermilab Instrumentation is developing a Ethernet field bus to communicate with a centralized middle layer utilizing Redis. Each embedded node will stream data to the middle layer where post processing can be done via micro services in containers. All data, including raw and processed wave forms, will...
ESS moved to CS-Studio Phoebus in 2019 and we have since then worked with the framework together with the community.
We have put in a lot of effort with the Logbook (Olog) and Save & Restore (based on MASAR).
IPv6 has been around since 1995, but EPICS has so far only supported IPv4. This will be a high level introduction to IPv6, what basic changes are necessary to existing IPv4 code, and what has been done for PV Access.
ACORN Human Factors: This presentation details an introduction to human factors and how Fermilab is enabling user-centered designs & processes for the ACORN project. Presentation topics include how a combination of design standardization and customization will enable more intuitive operations and reduce cognitive overwhelm & burnout.
A high-performance data acquisition system (DAQ) has been under active development to meet APS-U needs. It takes data from underneath FPGA (Field Programmable Gate Array), and streams it to its downstream users. The APS-U DAQ system software framework is implemented as a major portion of APS-U new control system software infrastructure, which is called C2. To visualize the DAQ data on the fly,...
This talk contextualizes EPICS in accelerator optimization and "quite
big" data experiment support, for other AI/ML session talks. EPICS 7
had the aim of better computing supporting for the next generation of
machines and analytical tools. Many new data types, such as matrices,
tables, images, and statistical descriptions, plus users' own data
types, now supplement the simple scalar and...
Machine Learning is a field of study that uses advanced algorithms and mathematical models to enable computers or machines to learn from data and make predictions or decisions without being explicitly programmed. In ML, data is used as a basis for training algorithms or models, which then analyze the data and identify patterns or relationships within it. These patterns are used to make...
This talk will include
- Discussion on FPGA-based system architectures, used in current AI/ML projects for accelerator applications.
- Lessons learned about interfaces along data signal path will focus on READS project.
A high-volume, time-series, database for experimental data. Presentation of initial work carried out by Osprey DCS towards providing a specially designed timeseries database that can ingest and correlate data at high-speed, and can be used to feed ML systems.
An overview of Machine Learning Operations (MLOps) for accelerator control.
This talk will cover the use cases, experience, and experimental results from using Machine Learning enhanced modeling and tuning methods at SLAC National Accelerator Laboratory and collaborating accelerator facilities. These applications range from intelligent online optimization with minimal prior data to deployment of fast-executing surrogate models to predict complicated beam dynamics...
Live observation of synchronized accelerator and photon data is crucial for best use of machine development time, and to setup demanding FEL configurations for the users. A Matlab class and a GUI have been developed and used in the last decade at the LCLS to acquire accelerator and photon data from different sources via EPICS and to present them. Data are synchronized on a pulse-to-pulse...
ChannelFinder started as a simple directory service to address some of the limitations of EPICS's flat name space. Over the past few release the ChannelFinder infrastructure has expanded to provide additional features to manage the configuration of multiple services to supporting a pvAccess name server.
Recent work on PVXS, including to as a replacement for pva2pva.
EPICS Base 7.0.7 was released in September 2022, and the changes introduced there were described in a talk given by Ralph Lange at the EPICS meeting in Slovenia.
