Effects of laser polarization on magnetic field time evolution in gold-coated hollow cylindrical hydrogen targets

Abstract

Techniques for generating energetic ions and amplifying magnetic fields continue to gain interest due to their applications in several fields such as medical, laboratory astrophysics, and inertial fusion research. A recently proposed scheme for this is Microtube implosion, which produces high density energetic ions and generate strong localized magnetic fields by utilizing high intensity lasers. In this study, we explore the effects of laser polarization on the magnetic field time evolution of gold-coated hollow cylindrical hydrogen targets with and without a seed magnetic field. Our 2D EPOCH simulation results show that in the presence of a constant seed magnetic field of Bi = 10 kT, using p-polarized lasers result in a localized magnetic field favoring the positive z direction.
