Abstract
A novel excitation scheme for Kr2 rare-gas excimer formation is developed. A pulse discharge excited Kr jet is dynamically mixed with a H2 neutral gas flow located downstream in a vacuum chamber. Rapid contact cooling of the high temperature Kr plasma jet by H2 gas collisions increases the Kr2 excimer emission at 148 nm by a factor of more than three compared with that observed without the cooling downstream. Significant decreases of both electron temperature and density in the Kr plasma when mixed with H2 gases downstream are measured with time-resolved spectroscopic methods
