Streak Camera 101: Visualizing Charged-Particle Beam Dynamics

Radiation generated by high-energy particle beams such as optical transition radiation (OTR) and optical synchrotron radiation (OSR) is widely used to characterize the beam properties. It has enabled dual-sweep streak cameras to visualize charged-particle beam dynamics. In this introductory paper, we will discuss properties of dual-sweep streak cameras and basic optics systems for imaging charged-particle bunches at different projection angles to produce top view, side view, and front view. Examples will be used to illustrate the beam dynamics that streak images reveal. We will also discuss practical considerations of optical transport line design to preserve spatial and temporal resolution of the camera system
