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 Booster_to_Storage_Ring(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.

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.
