Toroid Output vs Input Pulse Width

(370, 3700, and 37000 microsecond pulses)

Because the previous simulations showed that including buckets had only a tiny effect on the output signal, and since including them involves a significant sacrifice of both speed and disk space, these last three runs do not include the buckets.

370 us pulse without buckets

This is the plot of the input pulse to the toroid.

The plot on the left shows the signal coming out of the toroid, and the one on the right shows the magnitude of the undershoot resulting from the decay of the output signal. Note that its amplitude is larger than it was for the 37us run. It turns out that it is roughly proportional to the charge contained in the input pulse. (for pulses shorter than 2 ms -- see below)

3700 us pulse without buckets

This is the plot of the input pulse to the toroid. This is approximately the same width a real ping will have.

The plot on the left shows the signal coming out of the toroid, and the one on the right shows the magnitude of the undershoot resulting from the decay of the output signal. Note that its amplitude is larger than it was for the 370us run.

37000 us pulse without buckets

This is the plot of the input pulse to the toroid.

The plot on the left shows the signal coming out of the toroid, and the one on the right shows the magnitude of the undershoot resulting from the decay of the output signal. Note that the decay due to the L/R time (1.055/50, or about 2ms) of the toroid is starting to have an effect on the amplitude of the output signal, most noticeable in the undershoot...
