FIG. 1.

(Color online) Laser-driven reconnection experiments, view from the top. The lasers enter obliquely to the page, striking a foil target which is in the plane of the page.

(Color online) Evolution of n, B, and j in a simulation at Rutherford-like parameters. Top row: initial condition. Middle: , bottom: .

Image of FIG. 3.
FIG. 3.

(Color online) Evolution of n, , and the reconnection rate in the Rutherford simulation with (red, dashed) and without (blue, solid) collisions.

(Color online) Evolution of n, B, and j in a simulation at Omega-like parameters. Top row: initial condition. Middle: , bottom: .

Image of FIG. 5.
FIG. 5.

(Color online) Current sheet formation in the Omega-like simulation, at time , immediately before reconnection begins. (a) ; (b) reconnecting component ; (c) out-of-plane (Hall) fields ; (d) electron temperature (evaluated from the trace of the pressure tensor).

(Color online) Evolution of n, , and the reconnection rate in the Omega simulation.

Image of FIG. 7.
FIG. 7.

(Color online) Spitzer problem benchmarking of the collision operator. The plasma current is initially zero when an electric field (of order 0.05 of the runaway electric field) is imposed at t = 0. Top, red Z = 16; middle, green Z = 4; bottom, blue Z = 1. The dashed lines are the currents for the Spitzer analytic calculation in each case.

Tables

Table I.

Reported (or estimated) experimental parameters.

Generic image for table
Table II.

Parameters for Rutherford-like simulation. Reconnection parameters are evaluated in the simulation at , and are representative of the current sheet. is the length of the formed current sheet. For evaluating and quantities at the x-point are used, and is the peak value upstream of the current sheet.

Generic image for table
Table III.

Parameters for Omega-like simulation. Reconnection quantities are evaluated once the current sheet has formed at time , (Fig.5). They are calculated in the same way as described in Table II.
