“…Furthermore, researches show that a short and strong pulse signal can substantially reduce the system's temporal resolution while have little effect to the spatial resolution [1] . In our previous work, dynamic distortion based on on-line temporal system has been studied [9] . In this paper, we use the method of having weak signal to detect the streak camera's dynamic distortion to make the research of it, and by making different signal input forms, we study the distortion under different conditions.…”

Dynamic distortion, which is caused by space-charge effect, widely exists in streak camera. When input light intensity becomes too large, the electric field caused by electric beam turns out analogous to that caused by image converter tube, which leads to the dynamic distortion. In this article, we analyze the theory of the dynamic distortion by experiments and simulations upon CST Particle Studio software. Results show that: the intensity of current and the space position along the photocathode shall affect the dynamic distortion, leading to defocusing effect and reduce both the spatial resolution and the temporal resolution. All above assist us to better understand the electric-optic system of image converter tube, and provide ideas for further experimental diagnose design.

The influence of static vacuum on the cluster size and density of the supersonic gas jet is studied by Raleigh scattering method. It is found that in a range from 3×10-4 Pa to 9.9×104 Pa, the static vacuum has very little influence on the cluster size and desnity. The self-limiting effect which was found for hydrogen cluster at liquid nitrogen temperature is also found for argon cluster at positions far from the nozzle, and it is found to play an important role in the cluster generation and transporation. The result is very valuable for the construction of the desktop neutron source based on laser fusion method, since the pumps and device to supply the vacuum can be reduced and simplified.
