  NSLS-II is a 3 GeV ultra high brightness storage ring that is planned to succeed the present NSLS rings at Brookhaven. NSLS-II will provide hard X-ray photons from ~20 mini-gap undulators that may significantly contribute to the machine impedance. This, in combination with very high beam phase space density, and low momentum compaction drives a number of coherent instabilities. This paper reviews the most important collective effects for NSLS-II and their implications on the machine design.

  NSLS-II is a 3 GeV ultra-high brightness storage ring that is planned to succeed the present NSLS rings at Brookhaven. Ultra-low emittance bunch combined with a short bunch length results in the Touschek lifetime of only a few hours, which strongly advocates including harmonic RF in the baseline design of NSLS-II. This paper describes the required harmonic RF parameters, trade-offs between the possible choices and the expected system performance, including the implications on lifetime and instabilities.

The National Synchrotron Light Source at BNL was the first dedicated light source facility and it has now operated for more than 20 years. During this time the user community has grown to more than 2400 users annually. To insure that this vibrant user community has access to the highest quality photon beams, the NSLS is pursuing the design of a new ultra-high brightness (~10E21) electron storage ring, tailored to the 0.3-20 KeV photon energy range. We present our preliminary design and review the critical accelerator physics design issues.
