Triple-pulse X-ray spot size measurement of the Dragon-II linear induction accelerator
Yi Wang, Qin Li, Hengsong Ding +4
The Dragon-II linear induction accelerator is able to provide triple-pulse electron beams with an adjustable pulse spacing at the minimum of 300 ns. As a main determinant of the im…
Energy-spread measurement of triple-pulse electron beams based on the magnetic dispersion principle
Yi Wang, Qin Li, Zhiyong Yang +4
The energy-spread of the triple-pulse electron beam generated by the Dragon-II linear induction accelerator is measured using the method of energy dispersion in the magnetic field.…
Experimental observation of spatial jitters of a triple-pulse x-ray source based on the pinhole imaging technique
Yi Wang, Zhiyong Yang, Xiaobing Jing +3
In high-energy flash radiography, scattered photons will degrade the acquiring image, which limits the resolving power of the interface and density of the dense object. The applica…
Experimental comparison of various techniques for spot size measurement of high-energy x-ray source
Yi Wang, Qin Li, Nan Chen +7
In the experiment of flash-radiography, the quality of acquired image strongly depends on the focal size of the x-ray source spot. A variety of techniques based on imaging of pinho…
Spot size measurement of flash-radiography source utilizing the pinhole imaging method
Yi Wang, Qin Li, Nan Chen +4
The spot size of the x-ray source is a key parameter of a flash-radiography facility, which is usually quoted as an evaluation of the resolving power. The pinhole imaging technique…
