From: Electron heating in rf capacitive discharges at atmospheric-to-subatmospheric pressures
Nanosecond-resolved visualization of the electron heating structure. Spatiotemporal evolution of 514.5-nm continuum radiation (1st column), Te (2nd column), Ar I emission (3rd column) at (a) 760 Torr, (b) 400 Torr, (c) 300 Torr, (d) 200 Torr. The intensities of the continuum radiation and Ar I emission are normalized by the maximum intensity, and the unit of Te is eV. Color bars are located on the right side of each image.
