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Φ25mm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。
The beam parameter measurement of high energy and high intensity pulsed electron beam is an indispensable part of the development and debugging of the accelerator. It has extremely high requirements on the measurement equipment, and must have high time resolution, high anti-interference ability and high sensitivity Other properties. In order to meet this requirement, a new high-performance ultra-high speed three-segment camera has been developed. The split-frame camera adopts a full-aperture spectroscopic principle of converging optical imaging with better imaging quality, and combines the technologies of high-speed image intensifier, scientific CCD camera and large-scale integrated circuit to make it have the advantages of shutter time and amplitude time The ability to control independently and the flexible control method well meet the various test requirements in commissioning and achieve a maximum shutter speed of about 3 ns with an effective image area of Φ25 mm and better than 35 lp / mm Like the surface spatial resolution, the successful completion of a strong pulsed electron beam debugging.
