A simple study of gas heating effect for argon lamp

Gas temperature in the cathode region of a dc glow discharge with a thermionic cathode

“…Therefore, the physical processes in the cathode region (CR) play an important role in mercury-free fluorescent lamps on the basis of xenon low pressure glow discharges. The extensive literature that exists on this subject is concerned with theoretical and experimental studies on the CR in low pressure gas discharge lamps with mercury as carrier gas [1][2][3] and on Grimm-type glow discharges in argon [4][5][6][7][8][9][10] and helium [11]. Only a limited number of investigations studied hot cathode glow discharges and especially the gas temperature in the vicinity of the cathode [12].…”

Effect of growing nanoparticle on the magnetic field induced filaments in a radio-frequency Ar/C2H2 discharge plasma

“…For the whole set of chosen equation you can refer to. [22][23][24][25][26][27][28][29][30] In order to break the symmetry of the background plasma and excite the filamentary patterns, high density column of electron and ion is introduced to the center of the plasma. It is noted that the time required for the evolution of filamentary patterns is shorter if a larger perturbation is introduced into the plasma bulk so we assumed the perturbation column to have a density of 5 × 10 15 m −3 (i.e.…”
