Laser-driven hole boring and gamma-ray emission in high-density plasmas | | Evgeny Nerush
; Igor Kostyukov
; | | Date: |
13 Oct 2014 | | Abstract: | Ion acceleration in laser-produced dense plasmas is a key topic of many
recent investigations thanks to its potential applications. Besides, at
forthcoming laser intensities ($I gtrsim 10^{23} ext{W}, ext{cm}^{-2}$)
interaction of laser pulses with plasmas can be accompanied by copious
gamma-ray emission. Here we demonstrate the mutual influence of gamma-ray
emission and ion acceleration during relativistic hole boring in high-density
plasmas with ultra-intense laser pulses. If gamma-ray emission is abundant,
laser pulse reflection and hole-boring velocity are lower and gamma-ray
radiation pattern is narrower than in the case of low emission. Conservation of
energy and momentum allows one to elucidate the effects of gamma-ray emission
which are more pronounced at higher hole-boring velocities. | | Source: | arXiv, 1410.3336 | | Services: | Forum | Review | PDF | Favorites | |
