Ep ~ I RPA (at very high intensitíes, light pressure accelerates)
Laser-driven Ion Acceleration
TNSA(Target Normal Sheath Acceleration)
high laser contrast (main/pedestal) short laser pulse (10s fs – few ps) still occurring when the pre-plasma is “localized” at the target front-side higher energy gain in metals (returning electron current for the recirculations of “hot electrons”).
TNSA
Ponderomotive Acceleration(Sweeping potential at the laser pulse front)
low laser contrast (dense pre-plasma) long laser pulse (10s ps – ns) long pre-plasma length (100s m – mm) high laser absorption in the pre-plasma almost no laser interaction with the solid target

Challenges & advanced source useChallenges & advanced source use
Electron accelerationExternal injection: development of effective electron beam loading techniquesUse of an all-optical injection scheme (colliding pulses)Use of a tailored longitudinal plasma density profileDevelopment of a multiple stage acceleration setup including laser and electron beam optics (synchronization of the laser and electron beams in several tens of meters is necessary!)
Proton/ion acceleration1.Improving the beam quality in terms of divergence and monochromaticity2.Increasing the beam stability (energy distribution, particle numbers, emittance)3.Optimizing the laser to ion conversion efficiency4.Use of ultrathin targets (very high contrast and circular polarization are needed)5.Beam handling & selection (either through target engineering or conventional solutions, e.g. micro-lenses or magnetic quadrupoles)
Diagnostic requirements and developmentStrong energy increase of the particles produced at extreme laser intensities (particles whose energies will range from MeV to tens of GeV)Huge particle number per shot per second (prompt current)Energy and beam spreading of produced particles (no unique detector can be used)Huge EMP
