Outline of Final Research Achievements

Ion acceleration with ultra-high intensity lasers is an active area of research with many applications, ranging from ultra-fast radiography of high energy density (HED) plasmas to isochoric heating of plasmas samples, ions sources for cancer therapy and the Fast Ignition approach to Inertial Confinement Fusion. The purpose of the research is to study the TNSA proton beam transport and energy deposition in dense plasmas, as well as the proton beam generation by multi-beam irradiation on target, using the LFEX-GXII laser facility at the Institute of Laser Engineering, Osaka University.
Characterization of the TNSA proton beam source generated by LFEX laser by irradiating thin foils. ii) Study of the influence of multi-beam irradiation on target, with particular attention to the effects of beam interference. iii) Study of proton beam transport in cone geometry using a hemi-shell for proton generation.
