SR monitor for the measurements of beam profile, sizes, and bunch length has been designed and constructed at the Shanghai synchrotron radiation Facility (SSRF). A water-cooled beryllium mirror is installed to extract the visible SR. This beryllium mirror was designed via thermal analysis based on ANSYS. The extracted visible SR is relayed to dark room by three mirrors. The measurement system includes, imaging system, SR interferometers (SRI), streak camera and fast-gated camera etc are set in the dark room. Both the horizontal and the vertical beam sizes are monitored by SRI, and bunch length and temporal profile of the beam are measured by streak camera. The existed system suffers with dynamic problem for beam physics studies. The commissioning of synchrotron radiation monitor system has been performed in SSRF since December, 2007. The results obtained at SSRF will be presented.

SSRF is a 432 m-circumference synchrotron light source with a 150MeV linac, a 3.5GeV full energy booster, and a 3.5GeV storage ring. Principal diagnostics systems have been installed and nearly all have been commissioned during past two years. Data have been obtained on beam position, beam profile, current, and synchrotron radiation diagnostics beamline on the storage ring. Multi bunch transverse feedback system has been applied on the ring. Results for the 150MeV electron beams in the linac, up to 3.5GeV in the booster, and 3.5GeV in the ring will be presented.
