Measurement of spatial resolution of 11 MeV proton radiography

摘要

Proton radiography experiment with a Zumbro lens system was carried out on an 11 MeV proton cyclotron.The experimental results show that the image blurring is improved markedly. Clear images and good spatial resolution of the density step edges are obtained, which is important for hydrotest experiments, and the spatial resolution can achieve ~100 μm.
