Determination of neutral particle concentration at erosion laser plasma expansion into vacuum
Abstract
Experimental setup and methods for erosion laser plasma neutral component by ion probing are described. Laser ion source was used. Time distribution of neutral particle density at 5 cm from a point of plasma forming at laser radiation flux density q in 2x10 sup 7 2x10 sup 9 Vxcm sup -2 range for various target materials were obtained. Obtained distributions were approximated by Maxwell velocity distributions.
