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

Table 1

For each aluminium filter thickness, the energy range where only the contribution of alphas is visible, is reported together with the spatial extension on the parabola trace.

Filter material	Filter thickness (μm)	(MeV)	(mm)	(mm)	(mm)
Al	10	2.9–3.9	9.5	11.0	1.5
Al	15	3.9–5.76	7.8	9.5	1.7
Al	18	4.4–6.8	7.2	8.9	1.7
Al	20	4.75–7.4	6.9	8.6	1.7
Al	30	6.4–10.5	5.8	7.4	1.6

and are the coordinates on the detector plane corresponding to the maximum and minimum alpha energy able to cross the filter ( = 0 corresponds to the pinhole image position).
