The measurements show that the voltage pulse rise time and amplitude across the gap, which were reconstructed from the incident and reflected waves agree well with the voltage pulse shape and This is an open access article published by the IET and CEPRI under the Creative Commons Attribution-NonCommercial-NoDerivs License (http://creativecommons.org/licenses/by-nc-nd/3.0/) amplitude (waveform 4, Fig.…”

“…The voltage divider from small diameter of metal disc [see (12) and (21) in Fig. 1] is used in [9] (RADAN pulsers) and in [16,26,28] (SLEP pulsers). For a voltage-type TDR, the reflected pulse V ref summarises with a flat-top incident pulse V in , and for example, for an open-type load and small dissipation in the duct, doubling of the amplitude (V ref + V in ) ≃ 2V in occurs at t > tr.…”

“…The use of gas-filled diodes and nanosecond high-voltage pulsers allows to comparatively simply obtain electron beams with a half-height pulse duration of ∼100 ps [13]. The accumulated experience seems to be insufficient for correct registration of pulses of an electron beam current, discharge current, and voltage across the gap having subnanosecond and picosecond durations [16][17][18][19][20][21][22][23][24][25][26][27][28].…”

The collectors for measuring the time profile of a current pulse of the runaway electron beam that are generated under atmospheric pressure are described. An analysis of changes in pulse shape depending on the bandwidth of the registration path with a temporal resolution of up to 20 ps was performed. It is shown that the electron beam detected behind small-diameter diaphragms has a complex structure, which depends on the parameters of the gas diode. There is a design of the current shunts with a temporal resolution of up to 100 ps in this study. Measurement techniques of voltage pulses with subnanosecond and nanosecond duration are briefly described. High Voltage

Generation of runaway electrons and X rays in an inhomogeneous electric field at high gas pressures

et al. 2016

View full text Add to dashboard Cite

Results of experimental studies of the amplitude–temporal characteristics of a runaway electron (RE) beam, as well as breakdown voltage and discharge current with a picosecond time resolution are presented. The maximum pressure, at which a RE beam is detectable, decreases with increasing the voltage rise time. The waveforms of the discharge and RE beam currents are synchronized with those of the voltage pulses. It is shown that the amplitude–temporal characteristics of the RE beam depend on the designs of the gas-filled diode and cathode, as well as the gap length. The mechanism for the generation of REs in atmospheric-pressure gases is analyzed on the basis of the obtained experimental data.
