MOPG004	NSLS-II Beam Intensity Measurement	26

	Beam intensity, also named beam charge or beam current, is one of the most important beam parameters for synchrotron light sources. At NSLS-II, there are at least two types of beam intensity monitors including Bergoz ICT, and Bergoz NPCT. The requirements of beam intensity measurements and the distribution of beam monitors are described. The EPICS-based controls and data acquisition systems for all intensity monitors are presented.

MOPG005	Controls and Data Acquisition for NSLS-II Loss Control and Monitoring	29
	Y. Hu, P. Cameron, D. Chabot, L.R. Dalesio, S.L. Kramer BNL, Upton, Long Island, New York, USA
	The NSLS-II Loss Control and Monitoring (LCM) system is safety-related, but not safety-credited. This definition and requirement makes implementation requirements of controls and data acquisition (DAQ) for the LCM less stringent. However, the LCM is one of the most complicated diagnostics subsystems since it involves so many components including beam intensity monitors, scrapers, and different types of beam loss monitors, and the component interacts with each other. The control & DAQ system design and prototype test results are presented.

	The NSLS-II Injector System Diagnostics will provide adequate instrumentation in the LINAC, and LTB (LINAC To Booster), to perform staged commissioning of NSLS-II LINAC. This instrumentation will provide sufficient diagnostics to determine bunch charge, length, transverse size, position, and beam losses. The LTB will include key instruments to be used for beam commissioning and tune-up, particularly, BPM, Beam Dumps / Faraday Cup, ICT, FCT, Flags, and Energy Slit. Measurements of beam charge, bunch train, bunch charge, energy jitter, emittance, and energy spread, as well as measurements for beam current, bunch train pattern, tune and chromaticity can be achieved. This paper will detail the implementation and status of these diagnostics components for the NSLS-II injector system.
