  Collider Accelerator Department at BNL is in the final stages of developing the 20-MeV R&D energy recovery linac with super-conducting 2.5 MeV RF gun and single-mode super-conducting 5-cell RF linac. This unique facility aims to address many outstanding questions relevant for high current (up to 0.5 A of average current), high brightness energy-recovery linacs with novel Zigzag-type merger. We present the performance of the R&D ERL elements and detailed commissioning plan.

  NSLS-II is a new ultra-bright 3rd generation 3GeV light source planned to be built at Brookhaven National Laboratory. The design of this facility is well under way. The requirement for the compact injector complex which has to continuously provide 3GeV electrons for top off injection into the storage ring is very demanding: high reliability, low loss, relatively high charge (10nC). The injector consists of linear accelerator, a full-energy booster, as well as transport lines and injection straight section. A large three dimensional dynamic aperture through the entire acceleration cycle in the booster synchrotron is required. Tolerances on pulsed magnets for the beam transfer are very tight in order to minimize injection losses and disturbance of the stored beam in the main ring. The components of the injector are optimized for high reliability and availability. In this paper we give an overview of the NSLS-II injector, discuss status, specifications and design challenges.
