High-dimensional chaotic attractors in a gyrotron with nonfixed field structure.

The chaotic dynamics of a gyrotron with nonfixed field structure is numerically simulated and the Lyapunov exponents of chaotic attractors are calculated. The dimensions of chaotic attractors estimated using the Kaplan-Yorke formula prove to be anomalously high. This fact is related to the presence of a large number of high- Q eigenmodes in the gyrotron resonator operating in the vicinity of a critical frequency of the electrodynamic system.
