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.

This paper presents the NSLS-II fast orbit feedback (FOFB) system, including the architecture, the algorithm and the commissioning results. A two-tier communication architecture is used to distribute the 10kHz beam position data (BPM) around the storage ring. The FOFB calculation is carried out in field programmable gate arrays (FPGA). An individual eigenmode compensation algorithm is applied to allow different eigenmodes to have different compensation parameters. The system is used as a regular tool to maintain the beam stability at NSLS-II.

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.
