  The NSLS-II Synchrotron Light Source currently under construction at Brookhaven National Laboratory is expected to provide unprecedented orbit stability in order to fully utilize the very small emittance of the electron beam. The required sub-micron resolution and stability motivated the development of new state-of-the-art Beam Position Monitoring (BPM) electronics. A fundamental aspect of the BPM system development leveraged the fact that dynamic thermal gradients are the dominant source of BPM position drift. The temperature dependent drift is predominantly introduced in the Analog Front End (AFE) electronics. Here we discuss the methods employed to enhance the heat transfer from the BPM Analog Front End and their effects on overall performance of the BPM electronic systems.

  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.

  The NSLS-II RF BPM development was undertaken to create a state-of-the-art BPM with the goal of exceeding capabilities and performance that has been demonstrated to date. The architecture of the RF BPM has been carefully conceived to provide a robust design with substantial flexibility to serve as a platform for other systems, one of which is the Cell Controller, which is used to process BPM data for fast orbit feedback.
