Modeling of a Liquid Leaf Target TNSA Experiment Using Particle-In-Cell Simulations and Deep Learning

Table 2

Table of the physical parameters to be optimized for the laser system. Both initial and optimized values are shown. Rows in bold remained fixed during optimization. The dimensionless laser amplitude also remained fixed during optimization to encourage the convergence towards nontrivial parameter combinations. is a measure for energy conversion efficiency (see equation (6)), normalized to the initial parameter case.
