As the newest and most advanced third generation light source, NSLS2 commissioning has started recently. A total of 50mA stored beam was achieved in the storage ring. Most of the diagnostic systems have been commissioned with beams and proved to be critical to the success of machine commissioning. This paper will present beam commissioning results of various diagnostic systems in the NSLS2 injector and storage ring, including profile monitors, current monitors, and position monitors. We will discuss some preliminary machine measurements as well, such as beam current and lifetime, tune, beam stability, filling pattern etc.

Visible Synchrotron Light Monitor (SLM) beamline has been designed and constructed at NSLS2 storage ring, to characterize the electron beam profile at various machine conditions. Due to carefully alignment, SLM beamline was able to see the first light even before beam circulating the ring. Besides a normal CCD camera to monitor the beam profile, streak camera and gated camera are used to measure the longitudinal and transverse profile to understand the beam dynamics. Measurement results from these cameras will be present in this paper.

NSLS2 Storage Ring transverse bunch by bunch feedback system has been designed to cure the coupled bunch instabilities, caused by HOM, resistive wall or ions. The system has been constructed, tested and commissioned with beam. Preliminary studies show that the feedback system can suppress single bunch instability. Mode analysis of the unstable coupled bunch motion reveals fast ion instability exist even at relative low current. The bunch by bunch feedback system performance will be presented in this paper.
