A fast-gated, image-intensified CCD camera was recently commissioned on the visible diagnostic beam line in SPEAR3. Although the system does not produce high-resolution images, the 2ns electronic gate and ability to generate multiple-exposure images provides good diagnostic potential. Furthermore, the addition of a rotating mirror just upstream of the camera photocathode provides the ability to sweep multiple images across a single frame during a single dynamical event. In this paper, we report on several fast-gated camera studies including (1) imaging of the injected beam with and without emittance-spoiling windows in the BTS transfer line, (2) horzontal and vertical single-bunch beam dynamics, and (3) images of short-bunch ‘bursting’ in low momentum-compaction optics.
