Paper Abstract

A framing camera based on the pulse-dilation technology is simulated by using the Monte Carlo method. The camera uses pulse dilation of an electron signal from a pulsed photocathode (PC) to achieve high temporal resolution. When the PC is not pulsed, the theoretical temporal resolution of the camera without pulse dilation is about 90 ps. When the excitation pulse is applied on the PC, the theoretical temporal resolution is improved to 1.9 ps using the pulse-dilation technology. The relationship between the temporal resolution and the PC bias voltage is obtained. The variation of the temporal resolution with the gradient of the PC excitation pulse is also provided. Furthermore, the connection between the temporal resolution and the drift length is acquired.
