Abstract
Measurements of the temporal and spatial resolution of a PS-1/S1 image-converter camera, depending on the scanning speed, were performed. The camera has a PIF-01 electron-optical converter with deflecting plates of the capacitor-type scan. It is shown that obtaining the minimum half-width of the space–time response function in two mutually perpendicular directions (time and space) can be achieved by selecting an optimal voltage at the focusing electrode. The difference between the optimal static and dynamic voltages of focusing in space and time was determined experimentally, which was 450 V for a scanning speed of 1.56 × 1010 cm/s. Computer modeling of the processes that affect the optimal resolution was performed.
