Optimum angle-cut of collimator for dense objects in high-energy proton radiography
《Chinese Physics C》2016年第2期102-106,共5页许海波 郑娜 
Supported by NSAF(11176001);Science and Technology Developing Foundation of China Academy of Engineering Physics(2012A0202006)
The use of minus identity lenses with an angle-cut collimator can achieve high contrast images in highenergy proton radiography.This article presents the principles of choosing the angle-cut aperture of the collimator...
