Thomson parabola ion traces.

TPS images (a,b) from the 25 nm Cu-particle coated target and the reference Cu-substrate respectively at 1.2 × 1018 W/cm2 laser intensity. The horizontal axis gives the deflection due to the electric field and the vertical axis is due to the magnetic field of the TPS. The applied electric and the magnetic field values are shown in the corresponding ion trace images. c,d shows a line profile through the TPS ion traces for both the targets. Each ionic species are labelled correspondingly.
