Univocal Discrimination of α Particles Produced by 11B(p, α)2α Fusions in Laser-Matter Experiments by Advanced Thomson Spectrometry

Figure 2

The ranges of carbon and alpha particles in aluminium are compared. The horizontal dotted line highlights the 15 μm range and the intercept with the alpha and carbon curves identifies the energy needed by the two types of ions to cross a filter of the mentioned thickness. Since the graph is plotted as a function of energy per nucleon, the where only alphas can cross the filter will correspond to a certain on the parabola trace where only the alpha particles are contributing to the signal.
