Abstract
Abstract A low inductance magnetic wiggler for use in electron beam type lasers generates a high intensity spatially periodic magnetic field. The wiggler is formed as a plurality of closed conductive loops having their centers spaced along a common axis. Adjacent loops are connected by a conductor extending parallel to the axis, the connecting conductors being positioned alternately on diametrically opposite sides of the loops.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
62 words
A low inductance wiggler for an electron beam laser comprising: a plurality of annular conductors having their centers spaced along a common axis, and a plurality of straight conductors, each pair of adjacent annular conductors being connected by one of said straight conductors, the straight conductors extending parallel to said axis and being alternately positioned on diametrically opposite sides of said axis.
Claim 2
Dependent Claim
62 words
A low inductance wiggler for an electron beam laser comprising: a plurality of annular conductors having their centers spaced along a common axis, and a plurality of straight conductors, each pair of adjacent annular conductors being connected by one of said straight conductors, the straight conductors extending parallel to said axis and being alternately positioned on diametrically opposite sides of said axis.
Claim 3
Dependent Claim
37 words
The wiggler of claim 1 wherein the plurality of annular conductors and interconnecting straight conductors form a unitary rigid structure with an open passage extending along said axis through the central openings of all the annular conductors.
Claim 4
Dependent Claim
46 words
The wiggler of claim 1 further including a pair of conductors extending parallel to said axis and radially outside of said annular conductors, the pair of conductors extending the length of the wiggler and being connected to the annular conductor at one end of the wiggler.
Claim 5
Dependent Claim
52 words
A low-inductance magnetic wiggler for a free electron laser comprising an electrical conductor for conducting a current, the conductor being formed with successive portions extending alternately parallel to and transverse to a common axis, the transverse portions having openings therethrough, the openings of the transverse portions being aligned along said common axis.
Claim 6
Dependent Claim
52 words
A low-inductance magnetic wiggler for a free electron laser comprising an electrical conductor for conducting a current, the conductor being formed with successive portions extending alternately parallel to and transverse to a common axis, the transverse portions having openings therethrough, the openings of the transverse portions being aligned along said common axis.
Claim 7
Dependent Claim
12 words
Apparatus of claim 4 wherein the conductor is a rigid self-supporting structure.
