Investigation of microwave radiation from a compressed beam of ions using generalized Planck radiation law

Abstract

An ion-beam compressed by an external electric force is characterized by a unique non-equilibrium distribution function. This is a special case of Tsallis distribution with entropy index q=2, which allows the system to possess appreciably low thermal energy. The thermal radiation by such compressed ion-beam has been investigated in this work. As the system is non extensive, Planck law of radiation has been modified using Tsallis thermostatistics for the investigation of the system. The average energy of radiation has been derived by introducing the non extensive partition function in the statistical relation of internal energy. The spectral energy density, spectral radiation and total radiation power have also been computed. It is seen that a microwave radiation will be emitted by the compressed ion-beam. The fusion energy gain Q (ratio of the output fusion power to the power consumed by the system) according to the proposed scheme (R. K. Paul 2015) using compressed ion-beam by electric field will not change significantly as the radiated power is very small.
