Artificially Structured Boundary as a Charged Particle Beam Deflector Shield

The possibility of using a planar artificially structured boundary as a charged particle beam deflector shield is studied via classical trajectory Monte Carlo simulation. The artificially structured boundary (ASB) is formed by a planar array of permanent disk magnets with like poles facing out and creates a spatially periodic magnetostatic field. A mono-energetic beam of charged particles is incident on the ASB, and the conditions under which particles penetrate through the array are determined.
