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.

  Clocking an ADC is the most critical point when resolution is a major concern. Any fluctuations on the input clock performance correlates to jitter. The many different formats used to clock ADCs on the market makes choosing the appropriate one no easy task. LVDS, PECL, LVPECL, CMOS and CML are just some of the different types. With each type a certain matching network will be required. This paper will discuss the advantages of each format as well as its associated matching network.
