Absztrakt: Laser acceleration of ions from both solid and gaseous target
attracts a great attention because of its potential medical applications
including the hadron therapy. The recent development of ELI-ALPS facility
which will host the laser system capable of generating ultra-short pulses in
the multiterawatt or even petawatt power range at high repetition rate, which
is crucial for the investigation of new regimes of laser-matter interactions,
especially laser proton acceleration. The most stable and well understood
mechanism is the TNSA (Target Normal Sheath Acceleration), which usually
requires long pulse duration in order to reach high cut-off energy. Since at
ELI-ALPS the short pulses are in the center of interest, we have to consider
different mechanisms, where the RPDA (Radiation Pressure Dominant
Acceleration) is the driving process. The schemes of interest are the
collision-less Shock Wave Acceleration and Magnetic Vortex Ion Acceleration,
which is more efficient in near-critical density plasma.
