Microscopic analysis of filament in air
Abstract
This is the report on work to build a dual electron ion imaging system. Our main goal is to use this apparatus, beyond its standard operation as single ionization imaging, to capture the plasma and plasmonic forces and the contribution of field redistribution on the momentum of ejected electrons. In this apparatus the free electrons liberated by the laser pulse are removed from the interaction region with a strong repelling DC field. As they leave the interaction region their motion is driven by the static electric field towards a micro channel plate. The image is recorded with a CCD camera looking at the phosphor plate that converts the electron current to light. In our new design of VMI with additional plate, the resolution has improved ten times over that of the traditional design of Eppink.
