Abstract :
The ePLAS implicit simulation code1 is being used to study various focusing aids for hot electron directivity in Fast Igintion2. 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 eMHD3 effects, which can enhance B-field penetration in steep density gradient regions. The E- and B fields are determined by the Implicit Moment Method1.
