One of the distinguished features of the cathode sheath (CS) region of abnormal
glow discharges (GD) is the distribution of electric field strength F, which is of
crucial importance for charged particles acceleration, their trajectories, kinetic
energies and collisions with other particles and cathode sputtering. All these
processes are relevant for the operation of GD, as well as for numerous
applications in the field of spectroscopic analysis, plasma etching, thin film
deposition and depth profiling of cathode material. Thus, the importance of nonperturbing
technique for F distribution measurement in a tiny CS region was
recognized long time ago.
Within this work, a simple technique, based on the standard optical
emission spectroscopy (OES) and standard laboratory equipment, has been used
for F mapping in the CS region of abnormal GDs of Grimm type in argon and
neon. This is in essence the well known Lo Surdo technique used for studies of
Stark effect, but employed with ...a modern CCD detector [1-3].
The profiles of two neutral argon lines (Ar I 518.775 nm and
522.127 nm) and several neutral neon lines were observed in the CS region sideon
to the discharge axis. It was found that some of the studied lines manifest the
Stark splitting, and that all lines exhibit Stark shifts, whose measured values are
subsequently used for estimating the distributions of the electric field strength in
the cathode sheath region of the studied glow discharges.
