Development of high-power pulsed radiation sources in any frequency range requires both generation of high power to drive the source and increasing the efficiency of supplied power to radiated electromagnetic field conversion. The former implies the generation of high power (that is equal to high voltage and high current) pulses. The latter means the use of an electron beam moving in a vacuum to produce the intense radiation: high-electron beam current or high-current density combined with a large cross section of interaction area are required. Explosive pulsed power could contribute to both of the above being capable to store and deliver much higher specific energy as compared with either dielectrics or magnetics and providing high flexibility for matching with a load by the use of a pulse-forming network. Piecemeal matching of explosively driven power supply with the high-power microwave (HPM) producing load (vacuum tube) is described.

This study presents a channel-type multipacting cathode and employs the particle-in-cell (PIC) and Monte Carlo (MC) simulation methods to investigate the influence of various cathode parameters, including channel material, channel aperture, axial applied electric field, and initial input current on emission performance. All these parameters are found to significantly affect the output current density of the cathode and are further optimized. The optimized cathode can achieve an output current density of 380 A/cm2, significantly enhancing the output current density of the multipacting cathode and providing valuable theoretical support for the design of cathodes with high current density.

The measurement of square wave signals with sub-nanosecond (<1> $Omega $ effectively enhances the low-frequency performance of the probe. The “ringing” phenomenon of the loop under high-resistance load is further analyzed in this study. To achieve wideband measurement, waveform distortion is effectively suppressed by incorporating a damping resistor and limiting the length of the transmission signal line. Finally, by conducting electromagnetic field simulation, network analyzer inspections, and calibrating experimental standard signal generators, we demonstrated that the proposed coaxial pulse probe has a wideband range of 10 MHz–1 GHz, a leading-edge response time of approximately 350 ps, and a measurement error of less than 3%.

X-ray digital imaging technology can be used for visualization and nondestructive detection of power equipment, which is widely used in defect determination and anomaly detection. However, when X-ray is used for defect detection of power equipment, it remains to be investigated whether X-ray irradiation will deteriorate the properties of insulating materials or not. In this study, four kinds of insulating materials that are commonly used in power equipment, including alumina (Al2O3), epoxy/alumina (EP/Al2O3) composite material, polyether ether ketone (PEEK), and polyimide (PI), are irradiated with high-penetration and high-dose X-rays. The effects of irradiation time and atmosphere on the properties of insulating materials were studied systematically. The results show that the crystalline structure of inorganic materials and the chemical structure of organic materials are basically unchanged after X-ray irradiation. In terms of insulation properties that include dielectric property, surface flashover voltage, surface potential decay, and volume resistivity, it turns out that the insulation performance of the insulating materials tends to deteriorate after X-ray irradiation, while the degree of degradation is extremely low. In addition, the results of surface potential decay of EP/Al2O3 show that the X-ray irradiation would accelerate the dissipation of surface charge, which is in favor of the safety of power insulation.
