We present our efforts to develop a lightweight modular EPICS collector to record small- to medium-sized sets of PVs over a user-controlled period of time.

The goal is to provide an easy-to-extend Python package for recording PV data during experimental runs that covers basic requirements such as export-to-file, upload to data-management systems, and live-streaming of recorded data for...

20. A Versatile Framework for Automated Attitude Tuning at Light Source Facilities

Dr Pengcheng Li (IHEP)

Experiment control, data acquisition, data analysis, AI/ML

Lightning Talk

Attitude tuning—encompassing tasks such as beam focusing and sample alignment—is a critical yet time-consuming preparation step in synchrotron radiation experiments. This paper presents a Mamba-based software framework designed to automate and streamline attitude tuning at light source facilities such as HEPS and BSRF. The framework treats attitude tuning as a numerical optimization problem,...

76. Analysis and administration of an EPICS meeting using Python and maybe LLM

Alexis Gaget (CEA Paris-Saclay, IRFU)

Others

Lightning Talk

To manage this EPICS meeting, we had to switch between the Indico site and the Yurplan payment platform. To make administration easier, we wrote a Python script to check that participants had paid on the other platform.
At the same time, to get some basic statistics about the participants and their abstracts, we created a few additional scripts to analyze the conference.

Ensuring high availability of EPICS network services is increasingly important as control systems scale. By combining VRRP to provide IP‑layer mobility with Round‑Robin DNS for lightweight distribution, it is possible to build resilient configurations that tolerate client-side and server-side failures.
These techniques are commonly used for services such as load balancing provided by HAProxy...

3. EPICS (RTEMS/Linux) IOC with Web-Server for configuration

Heinz Junkes (Fritz Haber Institut)

System Management

Lightning Talk

I have often been asked by our IOC users whether it would be possible to configure and maintain the IOC via a web interface.
Just like they are used to doing with their internet routers (in Germany, fritz!box). This topic was raised at the last Codeathon/Documentathon at Diamond. I will briefly present what has been done so far and give an outlook on further steps.

22. Future State of SNCSEQ

Ralph Lange (ITER Organization)

EPICS Core

Lightning Talk

The EPICS SNCSEQ module (aka "SNL Sequencer") is getting close to its end of life: Finite state machines are limited and don't scale to the size of modern EPICS installations. Also, SNCSEQ does not understand the PVAccess network protocol.
But: It is performant, robust and stable. Almost every site is using it.

A possible future of SNCSEQ would restrict it to running local state machines...

Lightning Talk

Although the EPICS framework is used for many experimental physics facilities, monitoring the errors and warnings in IOC shell remains a challenge. Errors in the IOC shell are only kept track of in log files, which are rarely read by anyone. To address this issue, a project called IOC Shell Parser was developed, providing error detection and real-time EPICS monitoring. Designed to be used in...
