Potential for enhanced electron acceleration and plasma structure formation.
Identification of the whispering gallery effect in relativistic regimes.
Abstract
A relativistic laser pulse, confined in a cylindrical target, performs multiple scattering along the target surface. The confinement property of the target results in a very effcient interaction. This proccess, which is just yet another example of the "whispering gallery" effect, may pronounce itself in plenty of physical phenomena, including surface grazing electron acceleration and generation of relativistic magnetized plasma structures.
