Abstract: | The growth rate of the upper-hybrid waves with different velocities of superthermal electrons is computed considering a finite
temperature of the background plasma and relativistic corrections. Based on these computations two examples of high-frequency
zebra structures are interpreted. The sequence of the continuum, zebra structure, and continuum observed in the 29 October
2000, event is explained as an increase and following decrease of the velocity of superthermal electrons in the range of v=0.1–0.3 c. On the other hand, the zebra structure observed during the 18 March 2003 event represents an example with fast electron
acceleration. |
