A circular array of metallic wires, each carrying a current in the direction, out of the plane of paper.
The one-sector wedge with reflection boundary condition (a), which replicates the mode in an -wire cylindrical array (b). Here, .
(a) The unperturbed wire positions in a linear array, and (b) the perturbed wire positions in the presence of the mode. Here, is the displacement of the wire from its unperturbed position.
Acceleration vs displacement of the zeroth wire in the mode.
Normalized impact time vs initial azimuthal displacement of the zeroth wire in the mode. Also shown are the asymptotic formulas for [Eq. (12)] and approaching [Eq. (13)].
ALEGRA simulation geometry.
Amplitude gain as a function of time for the mode, with (a) , (b) , and (c) .
trajectory for the mode, with (a) , (b) , and (c) .
Geometry used for the simulations of the Cornell paired wire experiments. Note that the center-to-center spacing in these simulations is a wire’s diameter less than the nominal spacing in the experiments.
Results of discrete wire code simulations of the Cornell experiments, assuming all current flows in wire cores from . (a) Shows the results for the case, and (b) shows results for the case.
Results of the discrete wire simulations of the Cornell experiments, assuming current is “switched on” in the wires at into the current pulse. (a) Shows the results for the simulation, and (b) shows the results for a simulation.
Results of discrete wire simulations of the Cornell experiments showing the percent change in wire gaps for various assumed fractional amounts of the current pulse flowing in the wire cores. (a) Shows the results for the case, and (b) shows the results for the case.
