Computational study of laser-accelerated proton beam transport in solid density matters

Abstract

Laser-accelerated proton beams produced from a spherically curved target can be focused to exceptionally high density (10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">19</sup> −10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sup> particles/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ) and intense current (100s kA). The physics of such intense proton beam transport in solid-density matter is still not understood well and is important for high energy density physics.
