摘要：

We use the molecular dynamics computer simulation technique to study the behavior of electron plasmas in the presence of highly charged ions and strong magnetic fields. Such systems are encountered in electron cooler and electron target facilities, where large recombination rates have been observed. Our simulation results show enhanced electron densities in the vicinity of the ion, with the enhancement depending only weakly on the bulk density.
