Application of laser-driven capacitor-coil to target normal sheath acceleration

Over the previous decade, numerous experiments have been performed using a laser to drive a strong, quasi-static magnetic field. Field strength and energy density measurements of these experiments have varied by many orders of magnitude, painting a confusing picture of the effectiveness of these laser-driven coils (LDCs) as tools for generating consistent fields. At the higher end of the field energy spectrum, kilotesla field measurements have been used to justify future experimental platforms, theoretical work, and inertial confinement fusion concepts. In this paper, we present the results from our own experiments designed to measure magnetic fields from LDCs as well as a review of the body of experiments that have been undertaken in this field. We demonstrate how problems with prior diagnostic analyses have led to overestimations of the magnetic fields generated from LDCs.

A relativistic intensity laser pulse with energy from 25 to 130 J was used to produce strong magnetic fields in interactions with the designed no-hole capacitor-coil target. The magnetic field was estimated by the proton deflectometry method ignoring the potential influences of electric field. The proton deflection profiles in experiments are in good agreement with that by particle-track simulation with only the effect of coil magnetic field. The maximum magnetic field obtained in the experiment in the center of the coil is 117 ± 4 T. The experimental results with different laser energies are consistent with the previously found magnetic field production model in magnetic field amplitude and time sequence. It shows that the model has good prediction ability for magnetic field results. The results are beneficial to establish the experimental platform for generating a controllable pulsed magnetic field by relativistic intensity laser interaction. It potentially opens new frontiers in basic physics which require strong magnetic field environments.
