Special Issue Information

Dear Colleagues,

Pulsed power technology refers to electrophysical technology, where the energy stored slowly can be effectively released into a load instantaneously with a high power through compression on a time scale, transmission, and convergence in space. Pulsed power technology plays an important role in both civil and military applications because it can produce many kinds of extreme physical environments, such as high temperature, high pressure, high density plasma, strong shock wave, a high electric field, and intense radiation.

The Special Issue on “Challenges for Pulsed power Technology” aims to reflect recent developments in pulsed power technology, particularly in high-performance pulsed power components, novel circuit topologies, pulsed power facilities, and their applications.

Topics of interest include but are not limited to the following areas:

  • Fundamental research;
  • High voltage insulation and pulsed discharges;
  • Pulsed power switches and components;
  • Pulsed power systems;
  • High-energy density plasmas and applications;
  • Charged particle beam and accelerators;
  • High-power microwave and RF sources;
  • Plasma and pulse power diagnostics;
  • Repetitive frequency pulsed power technology;
  • Industrial/commercial/medical applications of pulsed power technology.
  • We hope the Special Issue can promote the development of pulsed power technology and communication between researchers.

X-ray sources based on pulsed electron accelerators stimulate the development of bremsstrahlung converter designs. The numerical optimization of transmission-type X-ray targets for maximum X-ray output by pulsed electron beams was carried out in the present work. The targets featured a combination of a heavy element (tungsten or molybdenum) X-ray conversion layer and a titanium membrane that served as the vacuum window, thermal shielding for converter heat, and an electron dump. The energy spectrum of the electron beam generated via explosive emission was analyzed via the space-charge effect, and was utilized for the source sampling algorithm for electron transportation simulation with a Monte Carlo method for X-ray emission analysis. It was revealed that the transmission photon intensity of a mono-material target is primarily affected by the thickness of the target, and there exists an optimal target thickness within which the photon fluence is restricted by insufficient electron stopping; when exceeded, the extra thickness of the X-ray converter target imposes absorption and attenuates the generated X-ray. Analysis on dual-layer targets proved that this optimized converter target thickness, combined with a proper titanium window, produces the highest X-ray photon emissions. Full article
