Direct measurements and modelling of neutral gas heating in a radio-frequency (13.56 MHz)
electrothermal collisional plasma micro-thruster have been performed using rovibrational band
matching of the second positive system of molecular nitrogen (N2) for operating pressures of
4.5 Torr down to 0.5 Torr. The temperature measured with decreasing pressure for 10 W power
input ranged from 395 K to 530 K in pure N2 and from 834 K to 1090 K in argon with 1% N2. A
simple analytical model was...[Show more]
