The SPEAR3 light source at SSRL was commissioned in 2004. Since that time the machine has undergone a continual program of improvements that has led to a lowering of the ring emittance, improved injection efficiencies, and the development of specialized operational modes. The effective use of beam diagnostics enabled these improvements to be tested and verified prior to their implementation. To optimize injection we needed to measure the beam position, size, shape, and arrival time of our injected bunch as well as beam losses in the ring. To test new lattices we used these diagnostics to characterize the non-linear resonances in the ring and therefore find operating points that maximized beam stability and lifetime. In this paper we discuss the electrical and optical instruments as well as the experimental methods we used to make these measurements.

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.
