Schematic of the experimental setup. Only the rear-side interaction pulse is shown.
Temporal profile of the ns interaction pulse as obtained on a streak camera. The relative delays at which the deflectograms shown in this manuscript have been taken are overlaid on the profile, with reference to the figure numbers.
(a) Typical face-on probing deflectogram in rear interaction configuration using 5.5 MeV protons, magnification . (b) PTRACE simulations for the conditions of (a) assuming the toroidal distribution parametrized as in Eq. (3). [(c) and (d)] Same interaction conditions as (a) and (b) but front interaction, and 7 MeV protons. The parameters of the PTRACE simulations [see Eq. (3)] are , , , , , are . The polarity of is inverted in (d). The timing of the data shown corresponds approximately to the pulse peak.
(a) Face-on probing deflectograms in rear configuration taken at using 5.5 MeV protons, geometrical magnification . (b) The corresponding PTRACE simulation with parameters , , , , , and . [(c) and (d)] Same as (a) and (b) but at ; the simulation parameters in (d) are , , , , , and .
(a) Side-on probing deflectogram obtained simultaneously with the face-on image in Figs. 3(a) and 3(b): the corresponding PTRACE simulation.
MHD simulation with the CHIC code. Parameters are laser intensity , spot radius, and ion charge. Frames (a) and (b) show the magnetic field (in T) at and 100 ps with respect to the pulse peak, respectively.
