摘要
高能强流脉冲电子束的束参数测量是加速器研制及调试中必不可少的一部分,它对测量设备的要求极高,必须具有高的时间分辨能力、较高的抗干扰能力及较高的灵敏度等性能。为了满足这种要求,研制了一种新的高性能超高速的三分幅相机。该分幅相机采用一种成像质量较好的会聚光成像的全口径分光原理,再结合高速的图像增强器、科学CCD相机及大规模集成电路等技术,使其具有了快门时间和幅间时间独立控制的能力,灵活的控制方式很好地满足了调试中的各种测试要求,并且在有效像面面积达到[Φ25 mm]的情况下可以获得约3 ns的最高快门速度以及好于35 lp/mm的像面空间分辨率,圆满地完成了强流脉冲电子束的调试工作。
Abstract
The measurement of electron beam parameters is very important for a linear induction accelerator (LIA). The measurement equipments must meet the demands of high time resolution, high sensitivity and high stability. The ultra-high-speedperformance is especially the most important one.One kind of 3-frame framing camera with ultra- high-speed and high performance has been developed recently. The optical principle of the framing camera is based on splitting the focused imaging light beam in the field of image space. It features good imaging quality and high light energyefficiency. The gated image intensifier with high speed shutter, the scientific CCD camera and the high speed controller based on large scale field programmable gate array are the main portions. The shutter time and the frame interval time can be set independently. The effective image size is 25 mm in diameter. The highest shutter time is about 3 ns. The spatial resolution is better than 35 lp/mm inimage space.
