Semi-analytical approaches to study hot electrons in the shock ignition regime

The hot electron role in shock generation and energy deposition to the hot dense core is crucial for the shock ignition scheme, implying the need for their characterization at laser intensities of interest for shock ignition. In this paper, we analyze the experimental results obtained at the PALS laboratory and provide an estimation of hot electron temperature and conversion efficiency using a semi-analytical approach, including Harrach-Kidder's model.The hot electron role in shock generation and energy deposition to the hot dense core is crucial for the shock ignition scheme, implying the need for their characterization at laser intensities of interest for shock ignition.
