The discharge isbetween mesh anode and disc cathode. It has been found that the discharge is in the up-normal glowdischarge and also follows Child law. Experimental studies showed that the optimum spacing between themesh anode and disc cathode is 3.5 mm at the adopted spectrum. The discharge current variation with thespacing between electrodes has a peak value of 20 mA at 3.5 mm for the same applied voltage and gaspressure. Several microwave frequencies radiated from the system have been observed. The radiatedpower for the different frequencies has a peak value at nitrogen gas pressure of 0. 7 Torr and 3.5 mmelectrodes spacing.}, keywords = {Vircator,DC-Discharge,Microwave Frequency}, url = {https://icmep.journals.ekb.eg/article_29917.html}, eprint = {https://icmep.journals.ekb.eg/article_29917_f0b9629a76d37cc2f277967b5d2265ba.pdf} }
