Abstract
Proton radiography is a common diagnostic technique in laser-driven magnetic field generation studies. It is based on measuring proton beam deflection in electromagnetic fields induced around the target with the help of radiochromic film stacks. Unraveling information recorded in experimental radiographs and extracting the field profiles is not always a straightforward task. In this paper, some aspects of data analysis by reproducing experimental radiographs in numerical simulations are described. The approach allows determining the field strength and structure in the target area for various target geometries.
Highlights
Strong magnetic field generators potentially have a number of applications in different areas of science and technology
Results for model targets proton radiography is discussed in application to several model targets
One of possible geometries is hollow targets with curved internal surface – “snail-type” targets, which have already demonstrated their potential for strong quasi-stationary magnetic field generation [10,11]
Summary
Strong magnetic field generators potentially have a number of applications in different areas of science and technology. The proton beam is directed to come through the region of interest, where the main laser pulse interacts with the studied target.
