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...
Overview of a bug found in pvaccess that created zombie threads and was affected by both Phoebus and the Archiver Appliance in different setups.
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 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.
This enables fast and configurable propagation of...
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...
