Abstract

The pulse-dilation framing camera is modeled and the cause of its dilation non-uniformity is introduced, the influence factors of dilation uniformity is studied and the non-uniformity is quantitatively analyzed using relative errors. The research results show that the dilation uniformity along the photocathode(PC) is gradually get worse by decreasing acceleration energy, increasing gradient of dilation pulse and enlarging drift length. Especially, the most and minimal serious effects are the gradient and the drift length, respectively. When the length of the PC is 80 mm, the PC voltage is -2 kV and drift length is 0.4 m, with increasing the gradient from 1 V/ps to 5 V/ps, the dilating relative errors is increased from 20.9% to 620.2%. When the PC voltage is -2 kV and gradient is 4 V/ps, with increasing drift length from 0.4 m to 0.8 m, the relative errors is increased from 261.5% to 269.6%. The research is discussed the deficiency of temporal performance in the pulse-dilation framing camera with large PC.
