The parameters of plasma and magnetic field are given in Table 1. The dashed line shows the dispersion curve of upper-hybrid waves - the oscillation branch with normal dispersion law ${\omega ^2\simeq \omega _{\rm p}^2+\omega _{\rm B}^2+3k_{\bot }^2v_{\rm T}^2}$ .

The dashed lines show the resonance curves corresponding to the maximal growth rate for the Bernstein mode with frequency ${s\omega _{\rm B}<\omega <(s+1)\omega _{\rm B}}$ at different values of cyclotron harmonic number l. The dotted contours show the distribution of background plasma electrons.

$\begin{figure} \par\includegraphics[width=7cm,clip]{2712_04.eps} \end{figure}$ Figure 4: Necessary conditions of Bernstein modes generation. The curve marked $(T_{\rm b})_{\rm opt}$ shows the required typical temperature of accelerated electrons, obtained from the Eq. (8); the dashed curve $(T_{\bot})_{\min}$ shows the required minimal value of the transversal component of electron temperature, derived from Eq. (9). The dependence of these values on the wave vector are calculated for the harmonic s=19, and the parameters of plasma and magnetic field given in Table 1. The dotted line shows the corresponding values of the parameter $\omega(\partial\varepsilon_{\Vert}/\partial\omega)$ .

$\begin{figure} \par\includegraphics[width=7cm,clip]{2712_05.eps} \end{figure}$ Figure 5: Necessary conditions of Bernstein modes generation: the dependence of the typical wave vector on the harmonic number for the different values of the accelerated electrons temperature. The parameters of plasma and magnetic field are given in Table 1. The dashed line, corresponding to the minimal possible value of the wave vector (9), is drawn for ${T_{\bot }=1\times 10^8}$ K. In the right bottom corner of the figure the points are shown, corresponding to the branch of oscillations with normal dispersion law.

The maximal transformation coefficient is shown, which corresponds to the transversal propagation of emission and extraordinary wave. The case s''=s' corresponds to the coalescence of waves of the same type; s''=s'+1 corresponds to the coalescence of waves of adjacent harmonics.
