  Abstract:  Recently, a simple diagnostic method based on lower hybrid waves was proposed to determine electron densities in magnetized plasmas. The diagnostic of the electron cyclotron resonance ion source plasma through these waves needs the stability analysis of magnetic mirror confined plasma. Using the electrostatic dispersion equation for a bi-Maxwellian distribution, the dispersion equation for a loss cone distribution was deduced. Under the experimental conditions corresponding to electron cyclotron resonance ion source plasma, the analysis of this equation indicates that in the spectral domain of the lower hybrid waves, the plasma is stable.
