How scientists use lasers to learn about the universe — plasma Learn about the PHELIX (Petawatt High-Energy Laser for Heavy Ion Experiments) laser at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany. PHELIX is used for plasma and atomic physics research.

A plasma jet is produced by running an electric arc between concentric electrodes while simultaneously injecting gas into that region. This process creates a hot, high-density plasma mixture that is then ejected from the device.1

These plasma jets are utilized for various chemical and metallurgical applications.1
