Figures

Image of FIG. 1.
FIG. 1.

(Color online) Magnetic field in “rigid beam” model calculation at 125 fs (top curve), 250 fs (middle curve), and 500 fs (bottom curve).

Image of FIG. 2.
FIG. 2.

(Color online) Target (left column) and fast electron density at (right column) in runs A–D (top–bottom). Run A is the control run, and runs B–D have the background composition determined by Eq. (7). In runs B–D, the fiber width is increasing.

Image of FIG. 3.
FIG. 3.

(Color online) Magnetic field in runs A and B at 250, 500, and (top–bottom). component of electric field in run B also shown. Run A is the control run.

Image of FIG. 4.
FIG. 4.

(Color online) Rate of magnetic field generation in run B due to term (top), and term (bottom) at 250, 500, and .

Image of FIG. 5.
FIG. 5.

(Color online) Target (left column) and fast electron density at (right column) in runs F-H (top–bottom). Runs F-H have their background composition determined by Eq. (9), and the fiber width increases from runs F to H.

Image of FIG. 6.
FIG. 6.

(Color online) Target (top left), fast electron density at (top right), and at (bottom left) in run J. Run J is identical to run F except that the material composition has been “reversed” so the fiber is now less resistive than the cladding material.

Image of FIG. 7.
FIG. 7.

(Color online) Resistivity vs temperature profiles used in cold target simulations: Fit to Milchberg for Al (black), Li for (blue), Li for (green), Li for (red).

Image of FIG. 8.
FIG. 8.

(Color online) Fast electron density and magnetic field at in runs K, L, and M. These are the “cold start” runs.
