A pulsed capillary discharge has been the subject of various experimental a
nd theoretical studies. A jet of copper-hydrogen plasma with a cylindrical
symmetry has been developed as a light source for spectroscopic measurement
s. The electron density of the plasma was obtained by using the H-beta spec
tral line of the hydrogen component plasma. The electron temperature was de
termined by means of the Boltzmann method applied to the copper profiles em
itted by the plasma jet. The copper and hydrogen lines were broadened princ
ipally by the Stark effect. The electron density of the plasma was found to
be about 2x10(17) cm(-3) and the electron temperature about 20000K.
