摘要
在工业辐照电子直线加速器的扫描线圈内通以准三角波电流能使电子束在扫描方向分布均匀。系统的扫描电流周期和调制器的主脉冲同步，可消除扫描均匀性中出现的拍频现象。根据速调管调制器主振脉冲频率、扫描宽度和电子束的束斑大小可以定出辐照床的最高运动速度以实现高效率的辐照。
The electron beams generated from the irradiation LINAC which is used for industry irradiation must be scanned. The current in the scanning coil should be quasi triangle wave to make the beams uniformity in the scanning direction. In the system the period of the scanning current is completely synchronized by the major pulse of the modulator in order to avoid the beat. The highest speed of the irradiation bed can be determined by the frequency of modulator, scanning width, and the size of electron beam spot to ensure the high efficient irradiation.
