Fig. 2. (a) Typical time-resolved ion current density observed using an IC positioned at a distance of 1.5 m from a massive target in a backward direction at with respect to the laser vector. The first peak was induced by XUV radiation. The peak at 70 ns was induced by 2.4 MeV protons. (b) Charge density of ions impacting on a secondary target at a distance of 10 cm for the primary target, which was derived from the IC signal using the relationship (2). The dashed line shows the energy of deuterons. The laser irradiance on target was .

Fig. 4. (a) Geometry of a nuclear reaction in the laboratory frame in which an incident deuteron with energy impinges on a Li atom of the stationary LiF target and angular distribution of the neutron energy calculated for a value of the reaction. (b) Deuteron energy dependence of the energy of d–Li neutrons detected in chosen directions as calculated using formula (1) in [10] describing the kinematics of neutron production in binary collisions between a projectile and an atom in a stationary target.

Fig. 5. Deuteron energy dependence of the neutron arrival time at detectors N1–N5 (see Figure 4) related to the laser–target interaction. The distances from the catcher LiF target to the scintillation detectors were , , and .
