“…Within the magnets, a pair of copper electrodes is separated by 2 cm (parallel); we here chose a parallel design instead of a wedged one, as proposed in Ref. 23, to favor an extremely high potential of 40 kV (±20 kV each side) without vacuum breakdown. 24 In the second part of the TPpredominantly used as drift and detector area-another pair of electrodes with a length of 30 cm and variable separation (wedged or parallel) can be added to further increase separation of traces in exchange for an increased low energy cut-off.…”

“…18 (hereafter referenced as "TP-H" with 0.57 T over 100 and 478 mm drift) and the TP described in Ref. 23 (hereafter referenced as "TP-C" with 0.6 T over 50 and 195 mm drift), both reflecting commonly used TP parameters for measuring ions from laser ion acceleration. Aiming for an energy resolution of better than 10% the TP-C only gives a feasible resolution at very low energies below 10 MeV/nucleon and the TP-H has reached its useability at 100 MeV/nucleon, while the new TP still gives a superior resolution below 5% at these energies.…”

Here, we report on the development of a novel high resolution and high dispersion Thomson parabola for simultaneously resolving protons and low-Z ions of more than 100 MeV/nucleon necessary to explore novel laser ion acceleration schemes. High electric and magnetic fields enable energy resolutions of ΔE∕E < 5% at 100 MeV/nucleon and impede premature merging of different ion species at low energies on the detector plane. First results from laser driven ion acceleration experiments performed at the Trident Laser Facility demonstrate high resolution and superior species and charge state separation of this novel Thomson parabola for ion energies of more than 30 MeV/nucleon.

Abstract. The charge particle emission form laser-generated plasma was studied experimentally and theoretically using the COMSOL simulation code. The particle acceleration was investigated using two lasers at two different regimes. A Nd:YAG laser, with 3 ns pulse duration and 10 10 W/cm 2 intensity, when focused on solid target produces a non-equilibrium plasma with average temperature of about 30-50 eV. An Iodine laser with 300 ps pulse duration and 10 16 W/cm 2 intensity produces plasmas with average temperatures of the order of tens keV. In both cases charge separation occurs and ions and electrons are accelerated at energies of the order of 200 eV and 1 MeV per charge state in the two cases, respectively. The simulation program permits to plot the charge particle trajectories from plasma source in vacuum indicating how they can be deflected by magnetic and electrical fields. The simulation code can be employed to realize suitable permanent magnets and solenoids to deflect ions toward a secondary target or detectors, to focalize ions and electrons, to realize electron traps able to provide significant ion acceleration and to realize efficient spectrometers. In particular it was applied to the study two Thomson parabola spectrometers able to detect ions at low and at high laser intensities. The comparisons between measurements and simulation is presented and discussed.
