Abstract
Images of the spatial structure of a capacitively coupled hydrogen discharge are presented for various strengths of applied magnetic field. With increasing magnetic field, we find that not only does the distribution of emission change because of the confinement of the electrons by the magnetic field, but we also find dark-bands regions that form in the discharge. By using narrowband interference filters (~10 nm bandwidth), we examine how the relative optical emission centered on Halpha and Hbeta (with respect to the total optical emission) change with the applied magnetic field.
