Comparative study of noise in low-current Townsend discharge in nitrogen and argon.

Noise in a low-current Townsend discharge in argon and nitrogen is studied. Experiments were performed in a "semiconductor-gas-discharge" structure constituted by a short plane-parallel discharge gap and a high-resistivity photosensitive semiconductor electrode. The noise of optical emission from gas excited by the discharge was investigated with a photomultiplier.

Self-organized patterns in successive bifurcations in planar semiconductor-gas-discharge device.

The formation of dissipative structures is investigated in a planar semiconductor-gas-discharge device at room temperature. The width of the discharge gap is about 1 mm. The gap is filled with nitrogen at a pressure that corresponds to the discharge operation at the right branch of the Paschen curve.

Dynamics and stability of the Townsend discharge in nitrogen in narrow gaps.

This paper investigates the dynamics of the Townsend discharge in nitrogen in narrow gaps. To provide stability of discharge in a broad range of current, we apply a plane-parallel structure, one of the electrodes of which is made of a high-resistivity gallium arsenide. The results of experiments are analyzed in the framework of theory [Yu.

Control of a noise-induced transition in a nonlinear dynamical system.

Feedback control is applied to change conditions of a noise-induced transition in a nonlinear second order dynamic system. The mathematical model used in the analysis is a system of two-component equations describing operation of a semiconductor-gas-discharge image converter. The control algorithm is proposed using the speed-gradient method for a linearized model system.

Phase transition in an ensemble of dissipative solitons of a Turing system.

Numerical study of a two-component reaction-diffusion system where Turing spatial structures are formed has revealed the existence of phase transition between condensed and rarefied phases of dissipative solitons. The effect is due to the dependence of soliton structure on control parameters. The transition manifests a hysteresis, which gives evidence for the possibility of phases to coexist.

Multioscillatory patterns in a hybrid semiconductor gas-discharge system.

A planar pattern forming semiconductor gas-discharge device is examined. While being driven with a stationary voltage, it generates patterns that contain domains oscillating with different frequencies. The multioscillatory pattern is formed in a sequence of bifurcations from the homogeneous stationary state.
