The main factor that sharply decreases the efficiency 
of the employment of a pulsed-discharge xenon plasma as an emitter 
in electric-discharge sources of pumping of dye lasers is a macroscopic 
loss of stability of the discharge in the temperature and pressure 
ranges selected. It has been established that in the pressure range 
of 1-10 torr, an increase in the temperature of a pulsed-discharge 
xenon plasma results in the mechanism of conduction becoming purely 
collisional. Stabilization of macroinstabilities in the plasma has 
been attained using a sectioned return current conductor in a flash 
coaxial lamp. It has been verified by experiment that uniformity of 
the sectioning ensures a high degree of homogeneity of the electric-discharge 
plasma in the discharge space.
