摘要
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 (similar to 10 nm bandwidth), we examine how the relative optical emission centered on H-alpha and H-beta (with respect to the total optical emission) change with the applied magnetic field.
