MOP196	A Modular Architecture for Accelerator Instrumentation	459
	J.H. DeLong BNL, Upton, Long Island, New York, USA
	Funding: US Department of Energy With accelerated schedules and finite resources the development of a common open source platform for accelerator instrumentation is required. This effort has led to the development of a flexible architecture with clearly defined interfaces. The resulting platform is currently used to implement fast orbit feedback as well as the Beam Position monitors for NSLS-II. The design includes an embedded processor, digital signal processing resources and communications interfaces to controls, the timing system and other devices distributed throughout the accelerator complex. This new architecture promotes customization and design re-use and is presented as an Open Source Hardware development project.

	A new BPM (Beam Position Monitor) electronics is under development and in good progress at NSLS-II. This in-house BPM receiver with many new features is comparable to commercial solution. BPM data for fast orbit feedback (FOFB) is one of the most important physics applications. The procedure to use BPM for FOFB is introduced firstly. Then, different BPM data flows associated with different physics requirements and applications are discussed. And control implementation of BPM system for physics applications is presented.

	Funding: Work supported by the U.S. DOE under contract No. DE-AC02-98CH10886. An internal R&D program has been undertaken at BNL to develop a sub-micron RF Beam Position Monitor (BPM) for the NSLS-II 3rd generation light source that is currently under construction. The BPM R&D program started in August 2009. Successful beam tests were conducted 15 months from the start of the program. The NSLS-II RF BPM has been designed to meet all requirements for the NSLS-II Injection system and Storage Ring. Housing of the RF BPMs in ±0.1C thermally controlled racks provide sub-micron stabilization without active correction. An active pilot-tone has been incorporated to aid long-term (8hr min) stabilization to 200nm RMS.
