The proposed NSLS II light source* to be built at Brookhaven National Laboratory utilizes a LINAC and a Booster with a Storage-ring which share the same tunnel, but at different horizontal planes. The Booster which accepts beam from the LINAC, accelerates the electron beam to an energy of 3.0 GeV and the beam is extracted to the BoostertoStorageRing(BtS) transport line. The BtS line transports the beam and injects it into the Storage ring . In order to facilitate the design of the BtS transfer line, the line has been partitioned in three sections which can be considered as independent. The function of each the three sections will be discussed in details and the procedure for the design of the BtS line and other details about the optics and the magnetic elements of the line will be presented in the paper. The LINAC to Booster beam transfer line will also be discussed.

  Operation of the NSLS-II storage ring in the top-up mode requires highly reliable injection with low losses. In this paper we provide results of the injection simulations for the storage ring. The alignment tolerances as well as requirements for the injected beam parameters are also discussed.

  The NSLS-II injector consists of a 3 GeV booster injected by a 200MeV linac. Specifications of the linac are derived from Booster and Storage ring beam requirements. Linac design considerations are presented to meet these specifications.

We present conceptual design of the NSLS-II injection system. The injection system consists of low-energy linac, booster and transport lines. We review the requirements on the injection system imposed by the storage ring design and means of meeting these requirements. We discuss main parameters and layout of the injection system components.

  NSLS-II is a medium energy storage ring of 3GeV electron beam energy with sub-nm.rad horizontal emittance and top-off capability at 500mA. Damping wigglers will be used not only to reduce the beam emittance but also for broadband sources for users. Cryo-Permanent Magnet Undulators (CPMUs) are considered for hard X-ray linear device, and permanent magnet based Elliptically Polarized Undulators(EPUs) are for polarization control. Rigorous R&D plans have been established to pursue the performance enhancement of the above devices as well as building new types of insertion devices such as high temperature superconducting wiggler/undulators. This paper describes the details of these activities and discuss technical issues.
