Influence of electrode voltage on imaging performance of streak camera

The newly assembled streak camera can not achieve the optimal imaging at the designed voltage. How to achieve the coordination of multiple electrode voltages is the key to achieve the optimal imaging performance of the streak camera. The relationship between the imaging performance of the streak camera and the electrode voltage is deeply studied based on theoretical analysis and numerical simulation. It is found that the distribution of electrode voltages plays an important role in the imaging performance of the streak camera. The first anode has little effect on the position of the image plane, while the first focusing electrode and the second focusing electrode have significant influence on the image plane, and the adjustment of their voltages has the opposite effect in direction on the image position. The experimental platform was built for testing the streak camera, and the test results are consistent with that of the theoretical analysis. The adjustment of the image plane position and the optimization of the resolution performance can be achieved by the linkage adjustment of the focusing electrode voltage and the anode voltage, which is of great application value for optimizing rapidly the performance for the streak camera.
