For the NSLS-II synchrotron light source, a Booster synchrotron has been designed and produced by Budker Institute of Nuclear Physics. The Booster accelerates an electron beam from 200 MeV up to 3 GeV in both single-bunch and multi-bunch modes with repetition rate of 1 Hz. Accurate measurements of beam parameters are required during every work cycle to provide feed-forward tuning of the Booster. A set of beam diagnostic instruments has been developed for the Booster commissioning and operation. Six fluorescent screens are used for the first-turn beam observation. Electrostatic BPMs with signal processing electronics developed by BNL provide measurements of closed orbit and lattice functions as well as single-pass beam measurements for commissioning. A DC current transformer is used to measure average beam current and lifetime; the filling pattern is monitored by a fast current transformer. Two light-output ports are set up for observation of the beam image. Tune measurement system provides frequent measurements of betatron tunes during the energy ramp. Design and performance of the Booster beam instrumentation are presented; the commissioning plan is also discussed.
