Multi-electron-recombination rates estimated within dense plasmas

TL;DR

This paper estimates multielectron recombination rates in dense plasmas, highlighting their significance in simulations of plasmas generated by intense radiation, such as FEL or ICF environments.

Contribution

It provides the first estimation of multielectron recombination rates in dense plasmas under LTE, emphasizing their importance in plasma modeling.

Findings

Multielectron recombination rates can be high in dense plasmas.

These rates are crucial for accurate plasma simulations.

Recombination should be included in models of FEL and ICF plasmas.

Abstract

We investigate the rates for multielectron recombination within a dense plasma environment in local thermodynamic equilibrium (LTE). We find that these multielectron recombination rates can be high within dense plasmas, and they should be treated in the simulations of the plasmas created by intense radiation, in particular for plasmas created by intense VUV radiation from free-electron-laser (FEL) or for modelling the inertial confinement fusion (ICF) plasmas.
