Specific Experiment

There is a great interest in the study of p-11B aneutronic nuclear fusion reactions, both for energy production and for determination of fusion cross-sections at low energies. In this context we performed experiments at CELIA in which energetic protons, accelerated by the laser ECLIPSE, were directed toward a solid Boron target. Because of the small cross-sections at these energies the number of expected reactions is low. CR39 Solid-State Nuclear Track Detectors (SSNTD) were used to detect the alpha particles produced. Because of the low expected yield, it is difficult to discriminate the tracks due to true fusion products from those due to natural background in the CR39. To this purpose we developed a methodology of particle recognition according to their direction with respect to the detector normal, able to determine the position of their source. We applied this to the specific experiment geometry, so to select from all the tracks those due to particles coming from the region of interaction between accelerated protons and solid boron target. This technique can be of great help on the analysis of SSNTD in experiments with low yield reactions, but can be also generally applied to any experiment where particles reach the track detector with known directions, and for example to improve the detection limit of particle spectrometers using CR39.

Correlation Criterion

We have investigated Uranium ions interaction at energy 14.0 MeV /u incident on a Vanadium target using mica as nuclear track detector. The detector exposure was made from ions beam facility at UNILAC accelerator of GSI Darmstadt, Germany. The etched detector was scanned using an optical microscope. From the total binary tracks data events, elastic track events were separated using angular correlation criterion. The elastic scattering data have been separated from the binary events and used for the determination of quarter-point angle θ1/4 (grazing angle). Total and partial reaction cross-sections are measured using the statistic of inelastic two-pronged and higher multiplicity tracks. The experimental measured cross-sections are compared with the cross-sections calculated using sharp cut-off model. The theoretical prediction of reaction parameters of interacting heavy ions have also been determined, that are comparable with experimental measured values.
