Description

Plasma jets produced from targets with atomic numbers ranging from 5 to 82 have been investigated in detail. Theoretical modeling based on a radiative cooling instability has been used to successfully explain the experimental results. Optical shadowgrams and x-ray pinhole pictures strongly indicate a correlation between the jets and x-ray emission from plasma. Plasma jets are intense in materials such as copper, molybdenum, tungsten, and gold which are characterized by strong x-ray emission. Interferograms indicate a large increase in electron density in the region of plasma jets
