  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.

  At the European Spallation Source, PV Access has been selected as the default EPICS protocol. However, PV Access in the initial releases of EPICS 7 does not implement any access control of client requests. In order to be able to protect selected process variables (PVs) from write requests that may cause harm to the system, some type of access control is needed. This paper details how PV Access is extended to partially reuse the access control available in Channel Access, while at the same time providing additional features. It also explains how ESS intends to deploy and manage access control in terms of infrastructure, tools and responsibilities. Limitations of the access control mechanism are also discussed.
