High-power microwave sources applied to a directed-energy weapon can lead permanent damage by radiating concentrated energy in specific direction disturb or overload electronic equipment. The effect analysis on the target, such as electronics exposed electromagnetic pulse, should be considered an important factor determining performance of high-power and conducting experimental evaluations. In this study, magnetically insulated transmission line oscillator, one representative based vacuum...
Abstract Background Applications of nonthermal plasma have expanded beyond the biomedical field to include antibacterial, anti-inflammatory, wound healing, and tissue regeneration. Plasma enhances epithelial cell repair; however, potential damage deep tissues vascular structures remains under investigation. Result This study assessed whether liquid (LP) increased nitric oxide (NO) production in human umbilical vein endothelial cells by modulating NO synthase (eNOS) phosphorylation signaling...
In this paper, the underwater performance of atmospheric-pressure plasma jets with and without a porous dielectric material is compared. The comparison included multi-channel discharge jet that served to generate microdischarges in thereby increased density, single-discharge typical pen-type atmospheric pressure dielectric. analysis, electrical optical characteristics, concentration reactive chemical species, sterilization were characterized. was found effectively sterilize over 99.9%...
The cell-type continuous electromagnetic radiation system is a demonstration device capable of generating high-power millimeter waves specific wavelength and observing their effects on living organisms. It irradiates biological sample placed in 30 × 50 cm3 cell with the 3.15-mm-wavelength region (with an output ≥1 W) analyzes temperature change sample. A vacuum electronic device-based coupled-cavity backward-wave oscillator converts electron energy beam into radiofrequency (RF) radiates it...
To build a proton beam accelerator that can be applied to boron neutron capture therapy system based on an electrostatic accelerator, high-voltage direct-current (DC) power supply equivalent the generation of neutrons should provided. The symmetrical Cockcroft-Walton voltage multiplier method is suitable for stable acceleration in tandem this system. Before second step-up with circuit, design inverter prioritized by preponderantly considering first and resonance frequency. Moreover,...

The failure threshold time of semiconductors caused by the impact irradiated high-power electromagnetic waves (HPEM) is experimentally studied. A SN7442 integrated circuit (IC) placed in an emulator with a WR430 closed waveguide and HPEM generated from magnetron oscillator. state component observed light-emitting diode (LED) detector voltage measured component. As magnitude electric field varied 24 kV/m to 36 kV/m, falls 195 s 17 dependence (E) on (T) T~E−12 T~E−6.
