Transition from forward to radial emission of energetic protons from the rear side of a foil
X. Wang,Koshichi Nemoto,Takuya Nayuki,Yuji Oishi,Klaus Eidmann,A. A. Andreev,Kei Takano,K. Nishikawa,Takashi Fujii,Y. Takizawa +9 more
TL;DR: In this paper, a 10-Hz, terawatt Ti:sapphire laser system was used to study the transition of energetic proton emission from the forward to radial direction when the peak plasma density of a foil target is changed form overdense to underdens.
