| 摘 要： | 针对神光Ⅲ原型实验中出现的动态畸变现象，开展了条纹相机动态成像特性研究。结合实验图像，利用CST Particle Studio软件模拟了强信号下变像管的成像过程，结果表明：在强信号下，变像管的空间电荷效应会造成电子束聚焦点与理想成像面距离减小，使得图像的放大倍数变小，产生信号弯曲现象，并且这一现象随着电流强度的增加更为明显。

| Abstract: | Experimental results of SGIII prototype facility show that dynamic distortion exists in streak camera. Simulations indicate that, if input light intensity becomes too large, space charge effect in image converter tube shall affect the focus of the electron beam and decrease the magnification, which result in dynamic distortion. With increase of current intensity, the dynamic distortion becomes more evident. All above assist us better understand the electric-optic system of image converter tube, and provide ideas for further experimental diagnostic design. |
