The NSLS II project started control system development in 2007 and completed commissioning in 2015. New hardware, tools, and applications were developed throughout the project to meet the project goals. Significant developments included the fast orbit feedback system, service based physics applications, relational database tools, and an integrated operator environment Control System Studio (CSS). This paper will discuss the results of the developments that were undertaken and their use for the accelerator and beam lines, commissioning results, and lessons learned along the way.

At National Synchrotron Light Source-II (NSLS-II), a field-programmable gate array (FPGA) based global active interlock system (AIS) has been commissioned and used for beam operations. The main propose of AIS is to protect insertion devices (ID) and vacuum chambers from the thermal damage of high density synchrotron radiation power. This report describes the status of AIS hardware, software architectures and operation experience.

EPICS version 4 is a set of software modules that add to the base of the EPICS toolkit for advanced control systems. Version 4 adds the possibility of process variable values of structured data, an introspection interface for dynamic typing plus some standard types, high-performance streaming, and a new front-end processing database for managing complex data I/O. A synchronous RPC-style facility has also been added so that the EPICS environment supports service-oriented architecture. We introduce EPICS and the new features of version 4. Then we describe selected deployments, particularly for high-throughput experiment data transport, experiment data management, beam dynamics and infrastructure data.

FRIB, which is a new heavy ion accelerator facility to provide intense beams of rare isotopes is currently under construction at Michigan State University. Its driver linac accelerates all stable ions up to uranium, and targets to provides a CW beam with the energy of 200MeV/u and the beam power of 400 kW. The beam commissioning of the driver linac has been planned to start from December 2017. A new infrastructure is under development using service oriented architecture for physics applications, which is a 3-tier structure consisting of upper level, middle layer, and low level respectively. The detailed design and its current status will be presented in this paper.
