Hot electron focusing for Fast Ignition

The ePLAS implicit simulation code
¹
is being used to study various focusing aids for hot electron directivity in Fast Igintion
²
. The ePLAS model can follow a laser generated hot electron component (fluid or particles) through background plasma consisting of cold fluid electrons and ions. The code captures eMHD
³
effects, which can enhance B-field penetration in steep density gradient regions. The E- and B fields are determined by the Implicit Moment Method
