Electron-Sensitive CCD Readout Array For A Circular-Scan Streak Tube

Design considerations and feasibility of a self-scanned circular electron-sensitive CCD readout array to be incorporated within a circular-scan streak tube are discussed. For a scan diameter of 30 mm the circular array will comprise 3500 detector elements. Estimates of the performance characteristics are presented with particular reference to detection sensitivity and signal-to-noise requirements. This streak tube with integral readout is designed to have a temporal resolution l5 ps and will form an essential part of a future spaceborne laser ranging system.
