“…Fig. 6 shows a typical SiC spectrum recorded in time-of-flight (TOF) approach [17] for ions emitted irradiating with the IPPLM of Warsaw terawatt laser the GO+Au target. The focal position was optimized to obtain dense and hot plasma from the target and to maximize the ion acceleration in the forward direction.…”

“…Because of the ion acceleration is strictly connected to electrons, the fast electron transport has been analyzed by the monitoring of the proton bunch profile as a function of both space and intensity in the rear side of the target [16]. The online bunches monitoring was performed in Time of Flight (TOF) approach where ions propagate over a known [17] placed at 0° with respect to the normal to the target surface, in the forward direction.…”

Abstract.In the present work, we propose the production of a hybrid graphene based material suitable to be laser irradiated with the aim to produce quasi-monoenergetic proton beams using a femtosecond laser system. The unique lattice structure of the irradiated solid thin target can affect the inside electron propagation, their outgoing from the rear side of a thin foil, and subsequently the plasma ion acceleration. The produced targets, have been characterized in composition, roughness and structure and for completeness irradiated. The yield and energy of the ions emitted from the laser-generated plasma have been monitored and the emission of proton stream profile exhibited an acceleration of the order of several MeVs/charge state.

“…During the free expansion in vacuum of laser-generated plasma, the emitted ions are accelerated and their current signal was measured by SiC detectors [10] in time of fl ight (TOF) confi guration. Figure 2a shows the TOF signal for the gold target irradiated at 600 J pulse energy with a focal position of -100 m.…”

Multi-energy ion implantation from high-intensity laser

Abstract. The laser-matter interaction using nominal laser intensity above 10 15 W/cm 2 generates in vacuum non--equilibrium plasmas accelerating ions at energies from tens keV up to hundreds MeV. From thin targets, using the TNSA regime, plasma is generated in the forward direction accelerating ions above 1 MeV per charge state and inducing high-ionization states. Generally, the ion energies follow a Boltzmann-like distribution characterized by a cutoff at high energy and by a Coulomb-shift towards high energy increasing the ion charge state. The accelerated ions are emitted with the high directivity, depending on the ion charge state and ion mass, along the normal to the target surface. The ion fl uencies depend on the ablated mass by laser, indeed it is low for thin targets. Ions accelerated from plasma can be implanted on different substrates such as Si crystals, glassy-carbon and polymers at different fl uences. The ion dose increment of implanted substrates is obtainable with repetitive laser shots and with repetitive plasma emissions. Ion beam analytical methods (IBA), such as Rutherford backscattering spectroscopy (RBS), elastic recoil detection analysis (ERDA) and proton-induced X-ray emission (PIXE) can be employed to analyse the implanted species in the substrates. Such analyses represent 'off-line' methods to extrapolate and to character the plasma ion stream emission as well as to investigate the chemical and physical modifi cations of the implanted surface. The multi-energy and species ion implantation from plasma, at high fl uency, changes the physical and chemical properties of the implanted substrates, in fact, many parameters, such as morphology, hardness, optical and mechanical properties, wetting ability and nanostructure generation may be modifi ed through the thermal-assisted implantation by multi-energy ions from laser-generated plasma.

Abstract. Nanostructured targets, based on hydrogenated polymers with embedded nanostructures, were prepared as thin micrometric foils for high-intensity laser irradiation in TNSA regime to produce high-ion acceleration. Experiments were performed at the PALS facility, in Prague, by using 1315 nm wavelength, 300 ps pulse duration and an intensity of 10 16 W/cm 2 and at the IPPLM, in Warsaw, by using 800 nm wavelength, 40 fs pulse duration, and an intensity of 10 19 W/cm 2 . Forward plasma diagnostic mainly uses SiC detectors and ion collectors in time of fl ight (TOF) confi guration. At these intensities, ions can be accelerated at energies above 1 MeV per nucleon. In presence of Au nanoparticles, and/or under particular irradiation conditions, effects of resonant absorption can induce ion acceleration enhancement up to values of the order of 4 MeV per nucleon.
