Abstract

Abstract

The magnetic lens used in high energy proton radiography system can alleviate the degradation of resolution which is induced by multi scattering of protons. A magnetic lens used for 3.6 MeV protons produced from DD fusion reactions in the implosion region is designed based on the scaling law of beamline design. A similar object-image relationship as in geometrical optical is deduced. 3D particle tracing simulation is also carried out to demonstrate the object-image relationship of the magnetic lens.
