This work describes a glow discharge lamp of the Grimm type. The lamp proved to be stable
for periods up to about 2 hours. The intensity to background ratio of the Cu I 237.4 nm line from a
brass target was found to be 200. Analysis of the experimental results showed that the discharge
potential depends on the discharge current through a power law 
. K and S are
also power functions of the pressure P. Intensity was measured as a function of the lamp
operating parameters (V, i, and P). Self-absorption was shown to be insignificant. The
sputtering rate Q was found to vary with the lamp power W=Vi, Q=C Wm where C
and m are constants.
