Overview of Beam Instrumentation and Diagnostics for the NSLS-II Project

A new, ultra-bright 3rd generation light source, the NSLS-II Project, is planned to be built at Brookhaven National Laboratory. The light source being developed will have unprecedently small beam horizontal emittance and will provide the radiation sources with a brightness of 3 x 10²¹ photons/sec/0.1%BW/mm²/mrad². In this paper we present the detailed specifications and a comprehensive description of the planned beam instrumentation system and the first results of the ongoing instrumentation R and D activities on beyond state-of-the-art subsystems.
