“…This experimental evidence may be attributed to a probable rearrangement of the polymer chain spacings, consequently changing the registration properties of the ionizing particles, a-particles and fission fragments, and fast neutrons. Other research groups have also observed the nature of the mechanisms that cause changes in the track etch parameters due to thermal treatment [22][23][24][25][26]. Fig.…”

“…Te track diameter is related to the energy of the impinging particle, thus allowing reconstructing the energy distribution of the ion beam, as well as its fux [23]. Many studies describe the dependence of the track diameter with the energy of the diferent ions, mostly referred to protons, alpha particles, and carbon ions [23][24][25][26][27][28][29][30][31][32][33][34][35]. However, the calibration of CR-39 for other species such as boron and silicon ions is almost missing in the current bibliography.…”

Solid-state nuclear track detectors (CR-39 type) are frequently used for the detection of ions accelerated by laser-plasma interaction because they are sensitive to each single particle. To the present day, CR-39 detectors are the main diagnostics in experiments focused on laser-driven proton-boron (p11B) fusion reactions to detect alpha particles, which are the main products of such a nuclear reaction, and to reconstruct their energy distribution. However, the acceleration of multispecies ions in the laser-generated plasma makes this spectroscopic method complex and often does not allow to unambiguously discriminate the alpha particles generated from p11B fusion events from the laser-driven ions. In this experimental work, performed at the PALS laser facility (600 J, 300 ps, laser intensity 1016 W/cm2), CR-39 detectors were used as main detectors for the angular distribution of the produced alpha particles during a p11B fusion dedicated experimental campaign. Additionally, a CR-39 detector was set inside a Thomson Parabola (TP) spectrometer with the aim to calibrate the CR-39 response for low energetic laser-driven ions originating from the plasma in the given experimental conditions. The detected ion energies were ranging from hundreds of keV to a few MeV, and the ion track diameters were measured for etching times up to 9 hours. The goal of the test was the evaluation of the detectors’ ability to discriminate the alpha particles from the aforementioned ions. Within this study, the calibration curves for protons and silicon low energy ions are accomplished, the overlapping of the proton tracks and alpha particles is verified, and a methodology to avoid this problem is realized.
