Synthesis of Pd-Fe System Alloy Nanoparticles by Pulsed Plasma in Liquid

open access: yesNanomaterials, 2018
We synthesized Pd-Fe series nanoparticles in solid solution using pulsed plasma in liquid with Pd-Fe bulk mixture electrodes. The Pd-Fe atomic percent ratios were 1:3, 1:1, and 3:1, and the particle size was measured to be less than 10 nm by high ...

Pulse switching characteristics of MAGTs for pulsed power applications

open access: yesElectrical Engineering in Japan, 1993
AbstractFor pulsed power systems such as lasers and accelerators, semiconductor switches with their longer service life have actively been developed as replacements for thyratrons. The MOS‐driven thyristors are suitable for pulsed power applications because they have high‐power handling and fast turn‐on capabilities.

From concept to reality — A review to the primary test stand and its preliminary application in high energy density physics

open access: yesMatter and Radiation at Extremes, 2016
Pulsed power technology, whereas the electrical energy stored in a relative long period is released in much shorter timescale, is an efficient method to create high energy density physics (HEDP) conditions in laboratory.
