	At a time when virtually all accelerator control systems were custom developments for each individual laboratory, an idea emerged from a meeting between the Los Alamos National Laboratory developers of the Ground Test Accelerator Control System and those tasked to design the control system for the Advanced Photon Source at Argonne National Laboratory. In a joint effort, the GTACS toolkit concept morphed into the beginnings of a powerful toolkit for building control systems for scientific facilities. From this humble beginning the Experimental Physics and Industrial Control System (EPICS) Collaboration quickly grew. EPICS is now used as a framework for control systems for scientific facilities on seven continents. The EPICS Collaboration started from a dedicated group of developers with very different ideas. This software continues to meet the increasingly challenging requirements for new facilities. This paper is a retrospective look at the creation and evolution of a collaboration that has grown for thirty years, with a look ahead to the future.

TUCPR05	UX Focused Development Work During Recent ORNL EPICS-Based Instrument Control System Upgrade Projects	818

	Funding: Oak Ridge National Laboratory is managed by UT-Battelle LLC for the US Department of Energy The importance of usability and easy-to-use user interfaces (UI) have been recognized across many domains. However, the user-friendliness of scientific experiment control systems often lags behind industry standards in the flourishing user experience (UX) field. Scientific control systems can certainly benefit from these new UX research methods and approaches. Recent instrument control system upgrade projects at the SNS and HFIR facilities at Oak Ridge National Laboratory demonstrate the effectiveness of UX focused development work, and further reveal the need for more utilization of such techniques coming from the UX field. The ongoing control system upgrades are targeting the key facility-level priority of higher scientific productivity, and UX is one of the important tools to help us achieve this priority. We will highlight research methods and practices, introduce our findings and deliverables, and share challenges and lessons learned in applying UX methods to scientific control systems.

	Funding: U.S. Department of Energy Office of Science, under Contract No. DE-AC02-06CH11357 The integration of structured data and the PV Access network protocol into the EPICS toolkit has opened up many possibilities for added functionality and features, which more and more facilities are looking to leverage. At the same time however the core developers also have to cope with technical debt incurred in the race to deliver working software. This paper will describe the current status of EPICS 7, and some of the work done in the last two years following the reorganization of the code-base. It will cover some of the development group’s technical and process changes, and echo questions being asked about support for recent language standards that may affect support for older target platforms, and adoption of other internal standards for coding and documentation.

	Phoebus is a Java/JavaFX framework for creating state-of-the-art, next-generation desktop applications for monitoring and controlling EPICS systems. The recent developments in Java and JavaFX have made it possible to reconsider the role of the Eclipse Rich Client Platform (RCP) in the development of client applications. Phoebus’s aim is to provide a simple to use and yet "rich-enough" application framework to develop modular JavaFX desktop applications for the most recent Java platform. Phoebus is an extensible framework for multiple control system protocols. It provides features for developing robust and scalable multi-threaded client applications. Key features include event rate decoupling, caching and queuing, and a common set of immutable data types to represent controls data from various protocols. The paper describes the framework as used to implement applications and service for monitoring EPICS PVs. The benefits highlighted will provide the EPICS community a new development perspective.

	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract number DE-AC05-00OR22725. The CS-Studio alarm system was originally based on a relational database and the Apache ActiveMQ message service. The former was necessary to store configuration and state, while the latter communicated state updates and user actions. In a recent update, the combination of relational database and ActiveMQ have been replaced by Apache Kafka. We present how this simplified the implementation while at the same time improving performance.
