Distributed Information Services for Control Systems (DISCS) is a framework for building high-level applications for commissioning, operation, and maintenance of an experimental physics facility. It provides programmatic as well as graphical interfaces to its data and services. It is comprised of a set of cooperating services and applications, and manages data such as naming, machine configuratio ... More

For over ten years the beamline instruments at the ISIS neutron and muon spallation source have been operating successfully using a LabVIEW-based control system. However, a range of new instruments are being built, offering the potential to implement very complex experiments. For this reason, the long-term suitability of the control system was reviewed. Based on this review, it was decided that s ... More

The existing EPICS Database covers soft real-time applications in the range up to ~1kHz. What would it need to go beyond that? Which existing concepts would hold? Which would have to be replaced? This talk shows common features of existing real-time frameworks in the fusion community, and presents ideas for a deterministic processing engine in EPICS.

The SNS is in the process of converting from a Windows/Labview based control system to a Linux/EPICS based system for our instrument controls. I will present an overview of our computing infrastructure, EPICS device control, our use of CS-Studio as the main user interface, and our plans for the future.

We have developed a fast data storage and archiving system for the PAL-XFEL project. The system monitors around 5000 EPICS PVs, updated at 60Hz, most of which are scalars. The system keeps, at a minimum, 5 minutes of short-term history available for retrieval at any time. On the other hand, the system allows for long-term preservation of data from specific time intervals. This includes preservatio ... More

The beamlines at NSLS-II are among the highest instrumented, and controlled of any worldwide. Each beamline can produce unstructured data sets in various formats. This data should be made available for data analysis and processing for beamline scientists and users. Various data flow systems are in place in numerous synchrotrons, however these are very domain specific and cannot handle such unstruc ... More

The complexity of the FRIB control system requires high code quality while, particularly during the commissioning phase, short turn-around times are desirable. We will present the status of our efforts moving towards automated software builds, deploying and managing FRIB's controls infrastructure. The tools used in this process include a revision control system (Git), software packaging (for Debia ... More

Each NSLS-II beamline can generate 72,000 data sets per day, over 2 M data sets in one year. The large amount of data files generated by our beamlines poses a massive file management challenge. In response to this challenge, we have developed filestore, as means to provide users with an interface to stored data. By leveraging features of Python and MongoDB, filestore can store information regardi ... More

Ophyd is a Python-based framework for experiment control under development at Brookhaven National Lab and deployed for use on NSLS-II beamlines. The software supports device control, data collection and distribution, reciprocal space operations, integration with electronic logging, and more. Ophyd is coupled with searchable back-end storage and retrieval components, which together form an end-to-e ... More

Last year we installed a dual redundant master timing system at LANSCE. A fiber-optic fanout concentrator module acts as a switch to select which timing generator is used to control the accelerator. Each generator consists of two IOCs, which must fail over as a pair. We modified the redundant IOC software from DESY to be able to synchronize some PVs but not others, and allow both IOCs to control ... More

A serious drawback that exists today is the lack of comprehensive frameworks on which to develop high level applications on top of EPICS. The lack of modern alternatives to antiquated codes has stalled progress in control systems development and presents impending difficulties for both private and public users to maintain EPICS. In the past few years, controls engineers from different accelerator ... More

A study of absorbed dose in undulator magnets at SLAC's Linac Coherent Light Source (LCLS) was performed using RADFET dosimeters. An extrapolation of the dose rate observed with the present LCLS, at 120 Hz, to the 1-MHz rate planned for LCLS II suggests the new system's permanent magnets could have an unacceptably short useable lifespan. In order to study factors affecting integrated dose rate in ... More

The traveler and cable web applications have been actively developed at FRIB since the beginning of 2013. The traveler application V2 entered production usage in March 2014. FRIB cable data has been imported into the cable application in production since Dec. 2014. The traveler and cable applications shares a similar technology stack: node.js, Express, and MongoDB. In this talk, I will give a ... More

We present the status and future plans for DIIRT (Data Integration In Real-Time), the Java Connection layer used in CS-Studio, WebPODS and available to any Java program. The features in the new 3.0 release will be presented, including the improved support for services, the improved support for real-time formulas, improved color maps for intensity graphs and the integration with JavaFX.

There is an increasing interest to access data coming out of the control system through web technology. Use cases includes the integration with other web tools, applications on tablets/devices, office network live reports/status and off campus access for monitoring beamlines. WebPODS aims to provide a specification based on HTTP/WebSockets/JSON to access the data, a server implementation to act as ... More

caputRecorder supports the recording and playback of sequences of caputs. It records each caput as a python command, and a sequence of caputs as a python function (users call this a "macro"). caputRecorder can also serve as a simple user interface for delivering canned python functions to end users. caputRecorder communicates with users via an EPICS database, so it allows any EPICS record or chann ...
