| Abstract | ||||
| ABSTRACT A vircator powered by DC power supply has been designed , operated and tested. The discharge is between mesh anode and disc cathode. It has been found that the discharge is in the up-normal glow discharge and also follows Child law. Experimental studies showed that the optimum spacing between the mesh anode and disc cathode is 3.5 mm at the adopted spectrum. The discharge current variation with the spacing between electrodes has a peak value of 20 mA at 3.5 mm for the same applied voltage and gas pressure. Several microwave frequencies radiated from the system have been observed. The radiated power for the different frequencies has a peak value at nitrogen gas pressure of 0. 7 Torr and 3.5 mm electrodes spacing. | ||||
