A measurement of the spatial distribution of the electron density in a plasma was carried out. The electron density of the plasma axis was determined by the microwave radiation from the plasma. This procedure was applicable for the plasma column whose diameter was comparable with a wavelength. The plasma studied was a positive column whose diameter was about 8 cm, in helium at pressure of 0.7 mm Hg. A microwave interferometer was used in Kband and the receiver for microwave radiation in X-band. Experimental results obtained by the microwave method were compared with those by the Langmuir probe method, and a satisfactory agreement between the two results was obtained. (auth)
