Axially polarized radiation from a toroidal magnetic structure with an equatorial slot

A polarizing toroidal magnet structure, comprising:

• a permanent magnet toroid, having an outer shell composed of a plurality of cylindrical rings;
• said toroid having an equatorial slot extending about a periphery of said outer shell, a central hollow core and a toroidal axis perpendicular to said toroid, provides a magnetic field within said core;
• said magnetic field having a constant vertical component Bv and a periodic horizontal component Bh, said periodic horizontal component Bh alternating in a horizontal direction with respect to said toroidal axis;
• said constant vertical component Bv having an orientation parallel to said toroidal axis;
• an electron beam generating means injects an electron beam into said core, said electron beam generating synchrotron radiation having a circular electron path;
• said constant vertical component Bv causing said electron beam to maintain said circular electron path;
• said plurality of cylindrical rings being wedge-shaped to minimize a leakage of magnetic flux from said core;
• a prism is placed in proximity to said toroid;
• said periodic horizontal component Bh, due to the periodicity of said component, causes said electron beam to wiggle about said circular path and emit a wiggling radiation within said core in a vertical direction parallel to said toroidal axis;
• and
• said synchrotron radiation is polarized in a horizontal direction perpendicular to said wiggling radiation, said wiggling radiation and said synchrotron radiation being mutually orthogonal, and said prism permits selectively eliminating said wiggling radiation or said synchrotron radiation.
