Space Charge in Polyethylene under AC Electric Stress using the Pulsed Electroacoustic Method
, 2004 This paper reports on space charge in XLPE planar samples of approximately 220 ?m thick subjected to dc 30 kV/mm and 1 Hz, 10 Hz and 50 Hz ac 30 kVpk/mm conditions for 24 hours. Measurement of space charge was carried out using the pulsed electroacoustic

Measurement of beam energy spread in a space-charge dominated electron beam
Physical Review Special Topics. Accelerators and Beams, 2004 Characterization of beam energy spread in a space-charge dominated beam is very important to understanding the physics of intense beams. It is believed that coupling between the transverse and longitudinal directions via Coulomb collisions will cause an ...

Dynamic analysis of the extended space charge layer using chronopotentiometric measurements
Micro and Nano Systems Letters, 2020 In this paper, we experimentally verified the length (L ESC ) and the concentration (c ESC ) of the extended space charge (ESC) layer in front of the electrical double layer (EDL) using the chronopotentiometric measurement and the equivalent circuit ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

DC electric field distribution in planar dielectric in the presence of space charge [PDF]
, 2007 Electric field in a dielectric material under dc conditions is determined by conductivity of the material. It is well known that the dc conductivity is a function of both temperature and electric field.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy
Advanced Engineering Materials, EarlyView.Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Electron beam phase-space measurement using a high-precision tomography technique
Physical Review Special Topics. Accelerators and Beams, 2003 We report a measurement of the multidimensional phase-space density distribution of an electron bunch. The measurement combines the techniques of picosecond slice-emittance measurement and high-resolution tomographic measurement of transverse phase space.
