Microwave Emission from Non-Maxwellian Plasmas

Microwave Emission from Non-Maxwellian Plasmas

Microwave measurements of the radiation from a weakly ionized low-energy plasma immersed in a magnetic field show significant departures from the Kirchhoff-Planck law. The departures can be explained by taking account of the non-Maxwellian distribution of the radiating electrons. By comparing the me...

Zusammenfassung:Microwave measurements of the radiation from a weakly ionized low-energy plasma immersed in a magnetic field show significant departures from the Kirchhoff-Planck law. The departures can be explained by taking account of the non-Maxwellian distribution of the radiating electrons. By comparing the measured and calculated radiation temperatures we estimate the distribution of electron velocities and their mean energy. (auth)
