电子束扫描均匀度是辐照电子直线加速器的重要指标之一，采用无偏估计方法对电子束的扫描均匀度作校正是一种有效的方法。
The uniformity of electron beam scanning is one of the important indices of linear accelerator. Unbiased estimation is an effective method for scanning uniformity calibration.
在考虑到加速器束流强度稳定性的基础上，90 %扫描宽度的扫描均匀度可达到2 3%(规一化rms)。
When beam stability of accelerator is considered, scanning uniformity in 90 % scanning range can be 2.3 % (normalized RMS).
