Inferring Morphology and Strength of Magnetic Fields From Proton Radiographs
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Proton radiography is an important diagnostic method for laser plasma experiments, and is particularlyimportant in the analysis of magnetized plasmas. The theory of radiographic image analysis has heretoforeonly permitted somewhat limited analysis of the radiographs of such plasmas. We furnish here a theorythat remedies this deficiency. We show that to linear order in magnetic field gradients, proton radiographsare projection images of the MHD current along the proton trajectories. We demonstrate that in the linearapproximation, the full structure of the perpedicular magnetic field can be reconstructed by solving a steadystate inhomogeneous 2-dimensional diffusion equation sourced by the radiograph fluence contrast data.
