摘要:

Spatially resolved electric field measurements in the cathode region of a dc glow discharge in hydrogen are performed using polarization‐dependent Stark broadening of plasma‐induced emission of the Balmer lines. The large concentrations of excited atoms in the sheath provide an accurate, sensitive measure of discharge electric fields.
