电子辐照加速器束流扫描均匀化研究

Research of Homogenizing Scanned Beam of Electron Irradiation Accelerator

本文对标准三角扫描波形产生的扫描不均匀度进行了理论推导,并给出了直观的图形函数。由于扫描磁铁感性负载的特性,其方波输入电压的扫描波形本质上应为指数波形,对其进行了理论公式推导,结果表明,指数波形的扫描不均匀度与标准的三角波形的扫描不均匀度是相同的。

The formula of the scanning inhomogeneity by standard triangle waveform was deducted and the visual curve was given out. Because of the inductance impedance characteristic of the scanning magnet, the current waveform should be exponential when the input voltage waveform is standard square waveform. The deduction result shows that scanning inhomogeneity by the standard triangle waveform is same with that by the exponential waveform.
