How to overcome the intensity-scaling limitations of laser-driven proton acceleration in the TNSA-regime
Researchers from the Helmholtz-Institute Jena and the University of Jena have made important progress toward a better understanding of the process of laser-driven proton acceleration from thin foils. Based on these results, a significant future increase of the maximum available proton energy, a parameter which is of utmost importance for the realization of future envisaged applications of laser-driven proton sources, seems possible with the existing and soon available high-power laser systems.
In an extensive experimental campaign carried out with the POLARIS laser system, the researchers investigated the influence of large a number of laser and target parameters, such as laser-pulse energy, on-target intensity, prepulse-characteristics, and preplasma formation. Such an extensive parametric study became possible only due to the unique combination of laser parameters available at the POLARIS system - mainly a moderate repetition rate with at the same time comparably high laser pulse energies. Furthermore, the possibility to control, vary, and monitor these parameters for each shot allowed for a detailled analysis of the influence of each individual parameter but also the interplay between them. The experimental results and their interpretation were supported by a large number of numerical simulations, which allowed to verify the conclusions based on the experiment.
In their study, the researchers found that for the goal of further increasing the maximum proton energy it is not the best approach just to increase the on-target intensity further and further. On the contrary, it was found that beyond a certain threshold a further increase in laser intensity did not lead to a further increase in maximum proton energy, see Fig. 1.
This is due to the fact that the fastest protons, for which the acceleration process starts ever earlier, quickly outrun the region where the highest acceleration field strength is present, see Fig. 2. Therefore, only increasing the laser intensity renders the acceleration process less efficient. This finding may lend a plausible explanation for the fact that for almost two decades it was not possible to increase the maximum proton energy by a significant factor - despite the fact that the tremendous laser development achieved during the same time period should have allowed for more significant improvements.
However, when special care is taken towards a tailored preplasma-formation in combination with a well-adapted temporal shape of the laser pulse, this temporal mismatch between the generation and evolution of the acceleration field and the movement of the protons during their acceleration can be overcome. Therefore, the results from the present study are highly promising for future proton-acceleration experiments, in which all relevant parameters of the laser and the plasma target need to be taken into account. This might help to bring the envisaged applications of laser-driven proton pulses closer to reality.
