The uniformity of electron beam scanning is one of the important indices of linear accelerator. Unbiased estimation is an effective method for scanning uniformitycalibration.
It was an important way for reducing the cost of development and maintaining the uniformity of products to realize the universal of calibration software between different control platforms.
