The performance and details of design are discussed for impulse Tesla transformers with various numbers of primaries. Possible ways of parameter optimization are suggested.
The dynamics of high-voltage pulsed discharge in nitrogen is studied experimentally under the conditions as follows: gas pressure 30 to 60 atm; applied voltage 200 to 400 kV; rise-time of the initial pulse 0.4 to 20 ns. The results are compared with the data of other writers.
Aspects of design of a multi-sectional Tesla transformer (MTT) presented as a system with three primaries are discussed. Calculation and experimental characteristics of MTT, and its advantages (lower currents in the primary, higher efficiency together with lower duration of the period) in comparison with traditional TT are shown.
Current distribution in relativistic magnetron (RM) of 8-mm wavelength has been studied experimentally and with the help of 3D simulation. Existence of direct and return axial electron flows that sufficiently disturb to the RM operation is considered.
Tesla transformer (TT) operation is denoted by losses in primary circuit. The spark resistance of gas switch and its affect to TT performance are studied both experimentally and theoretically.
Design aspects and test results of high-pressure (60 atm) gas switch incorporating into high-voltage UWB coaxial forming line (with the output voltage of 200–600 kV, and rise-time of 0.2–0.4 ns) are considered.
Features of impulse reflectometry using sub-nanoseconds pulses are considered. Impacts of non-uniformities in the system to the measured signal parameters are analyzed. An algorithm for observed data processing that takes into account the test signal envelope and numerous reflections originating in non-uniform system is proposed.
Features and results of experimental parametrical study of high-voltage breakdown in dense dielectric media are considered. Influence of temporal characteristics of the test system to breakdown parameters of dielectric is shown. Design and performance data of voltage and current sensors together with algorithm for experimental data processing are discussed.
Features of impulse reflectometry of the sub-nanosecond range are considered. The influence of parameters of a probing signal in the ultrabroadband nonuniform systems on the results of measurements is analyzed. An algorithm of processing of measurement data that allows accounting of the shape of the probing signal and numerous reflections, originating from nonuniform systems, is proposed.
The characteristics of measurements of parameters of impulses of the subnanosecond range in the coaxial waveguides by capacitive dividers of different type are considered. Advantages of application of dividers with partial integration and procedure of subsequent numerical restoration of initial impulse are showed.
