Abstract

The results of direct observation of the initial phase of explosive electron emission using high-resolution X-ray radiography in X-pinch radiation are reported here. The confirmation of common “Ecton” theory was not found within achieved temporal and spatial resolutions. A mechanism involving the surface breakdown of whiskers that leads to plasma development is proposed.

Simulations of Explosive Electron Emission in Cathodic Arcs. Final Report for Phase I Project

Technical Report Kolobov, Vladimir

The objective of this SBIR Project was to develop a computational tool for industrial engineering of electric discharges controlled by explosive electron emission (EEE). The physics of multi-phase phenomena associated with self-sustained formation of explosive emission centers (ectons) is not fully understood [1]. Ectons have been extensively studied for vacuum arcs where the gaseous plasma is produced from evaporated electrode material injected into a vacuum [2]. Our research aimed to understand effects of gas pressure on ecton dynamics, formation of plasma jets, gas-phase ionization, electrical breakdown mechanisms, and electrode erosion by cathodic arcs under different operating regimes.

Use of synchrotron-based radiography to diagnose pulsed power driven wire explosion experiments

Journal Article Theocharous, S. P. ; Bland, S. N. ; Yanuka, D. ; ... - Review of Scientific Instruments

We describe the first use of synchrotron radiation to probe pulsed power driven high energy density physics (HEDP) experiments. Multi-frame x-ray radiography with interframe spacing of 704 ns and temporal resolution of < 100 ps was used to diagnose the electrical explosion of different wire configurations in water including single copper and tungsten wires, parallel copper wire pairs and copper x-pinches. Such experiments are of great interest to a variety of areas including equation of state studies and high pressure materials research, but the optical diagnostics that are usually employed in these experiments are unable to probe areas behind themore »« less

Point-projection x-ray radiography using an X pinch as the radiation source

Journal Article Shelkovenko, T A ; Sinars, D B ; Pikuz, S A ; ... - Review of Scientific Instruments

Using an X pinch as a source of radiation for point-projection radiography, it is possible to project a high-resolution (1--10 {mu}m) shadow image of dense plasma or test objects onto x-ray-sensitive film. The emission characteristics of X pinches composed of a wide variety of materials have been studied using several diagnostics. The pulse duration and shape of the x-ray bursts were measured in the 1.5--6 keV band using fast diamond PCDs and an x-ray streak camera with sweep speeds as fast as 10 ns for the full sweep (3.5 cm). To investigate the line and continuum radiation emitted by themore »« less

Multiframe point-projection radiography imaging based on hybrid X-pinch

Journal Article Tilikin, I. N. ; Shelkovenko, T. A. ; Pikuz, S. A. ; ... - Review of Scientific Instruments

This paper demonstrates the possibility of using a new configuration of the hybrid X-pinch to produce a set of spatially and temporarily separate x-ray bursts that could be used for the radiography of dynamic events. To achieve this, a longer than normal wire is placed between the conical electrodes of the hybrid X-pinch, and a set of small spacers (fishing weights) is placed along the wire. Each subsection of the wire then acts as a unique X-pinch, producing its own radiation burst from a small (∼3 µm) spot. The timing between bursts is 20–50 ns, and each is <2 ns in duration.more »« less

Time-resolved x-ray radiography of spark ignition plasma

Conference Kastengren, Alan L. ; Duke, Daniel J. ; Swantek, Andrew B. ; ...

Understanding the short-lived structure of the plasma that forms between the electrodes of a spark plug is crucial to the development of improved ignition models for SI engines. However, measuring the amount of energy deposited in the gas directly and non-intrusively is difficult, due to the short time scales and small length scales involved. The breakdown of the spark gap occurs at nanosecond time scales, followed by an arc phase lasting a few microseconds. Finally, a glow discharge phase occurs over several milliseconds. It is during the arc and glow discharge phases that most of the heat transfer from themore »« less
