Investigation of the possibility of using correlation reflectometry to determine the parameters of small-scale turbulence in the core of a tokamak plasma
Plasma Physics Reports - Tập 32 - Trang 443-460 - 2006
Results are reported from investigating the possibility of using reflectometry to determine the parameters of small-scale turbulence in the core of a tokamak plasma. In particular, the extent to which the reflectometric measurements are local is estimated. Experimental data from reflectometric measurements in the gradient zone, as well as the cross spectra and radial correlation functions, are pre...... hiện toàn bộ
Lý thuyết phi tuyến của các sóng liên kết được minh họa qua sự bất ổn định của chùm điện tử và plasma Dịch bởi AI
Plasma Physics Reports - Tập 38 - Trang 627-635 - 2012
Giai đoạn phi tuyến của sự bất ổn định của một chùm electron hình nhẫn tách rời về mặt không gian khỏi plasma hình nhẫn được nghiên cứu. Các phương trình mô tả các sóng liên kết cho tỉ lệ tùy ý giữa mật độ chùm và mật độ plasma được rút ra. Kết quả cho thấy sự bất ổn định đạt đến điểm bão hòa ở khoảng cách tương đương với vài tỉ lệ gia tăng không gian nghịch đảo. Sự bão hòa này được gây ra bởi phi...... hiện toàn bộ

Prebreakdown phase of an interelectrode discharge in wate
Plasma Physics Reports - Tập 30 - Trang 632-637 - 2004
Results are presented from experimental studies of the prebreakdown phase of an electric discharge between point (anode) and plane (cathode) electrodes immersed in water with different initial conductivity. When a high-voltage pulse is applied, the induced conductivity is detected in the discharge gap. Its value is one order of magnitude higher than the initial conductivity. It is shown that the i...... hiện toàn bộ
Specificities of one-dimensional dissipative magnetohydrodynamics
Plasma Physics Reports - - 2016
One-dimensional dynamics of a plane slab of cold (β ≪ 1) isothermal plasma accelerated by a magnetic field is studied in terms of the MHD equations with a finite constant conductivity. The passage to the limit β → 0 is analyzed in detail. It is shown that, at β = 0, the character of the solution depends substantially on the boundary condition for the electric field at the inner plasma boundary. Th...... hiện toàn bộ
On the resonance amplification of magnetic perturbations near the threshold of tearing instability in a tokamak
Plasma Physics Reports - Tập 41 - Trang 961-974 - 2015
Using a cylindrical model, a relatively simple description is presented of how a magnetic field perturbation stimulated by a low external helical current or a small helical distortion of the boundary and generating magnetic islands penetrates into a plasma column with a magnetic surface q=m/n to which tearing instability is attached. Linear analysis of the classical instability with an aperiodic g...... hiện toàn bộ
Role of the magnetic field in electron transportation in a beam-plasma generator
Plasma Physics Reports - Tập 36 - Trang 1173-1176 - 2010
The passage of a concentrated beam through the extraction system of a beam plasma generator is investigated on the basis of analysis of variations in the beam diameter and emittance. Evolution of these parameters is analyzed in the final section of the extraction device, which is characterized by the high density gradient of the supplied gas. Much attention is given to the influence of the magneti...... hiện toàn bộ
Surface Plasmon Resonances of an Axially Magnetized Plasma Column in the Presence of Collisional Loss
Plasma Physics Reports - - 2018
Surface plasmon resonances arising in the course of scattering of an H-polarized plane electromagnetic wave by an axially magnetized plasma column are analyzed. Main attention is paid to the behavior of these resonances in the presence of collisional loss in the magnetoplasma filling the scatterer. The frequencies, Q factors, and amplitude coefficients of the electromagnetic field of multipole sur...... hiện toàn bộ
Small-size controlled vacuum spark-gap in an external magnetic field
Plasma Physics Reports - Tập 41 - Trang 198-202 - 2015
It is demonstrated that the operation of a small-size controlled spark-gap can be controlled by applying a uniform external magnetic field. It is shown that the magnetic field of such a simple configuration efficiently suppresses the effect of localization of the discharge current after multiple actuations of the spark-gap.
Plasma kinetics of ethanol conversion in a glow discharge
Plasma Physics Reports - Tập 38 - Trang 913-921 - 2012
The mechanism of ethanol conversion in a nonequilibrium glow discharge has been studied. It is shown that molecular hydrogen is produced in reactions between ethanol molecules and hydrogen atoms in the initial stage and in reactions involving active H, CH2OH, CH3CHOH, and formaldehyde in the final stage. Comparison with experimental data shows that the kinetic mechanism used in these calculations ...... hiện toàn bộ
