A scaling law for plasma focus devices

Physics Letters A, 1981
Abstract The neutron yield N in plasma focus devices is scalable with the sheet current I s according to N ∼ I 3.2 s . The efficiency of the current transfer into the sheet can be computed by means of a scaling law based on a simple fluid model.

The initial phase in plasma focus devices

Plasma Physics and Controlled Fusion, 1993
A discussion of the initial phase in plasma focus devices is given, in the light of the available experimental and theoretical knowledge on this subject. The influence of this phase on the focus phase is also discussed.

Carbonitriding of silicon using plasma focus device

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2009
Carbonitride thin films have been deposited on silicon substrate by the irradiation of energetic nitrogen ions emanated from dense plasma focus device. The carbon ions are ablated by the irradiation of relativistic electrons from the insert material (graphite) placed at the anode tip.

Ion Acceleration Parameter of the Plasma Focus Device

IEEE Transactions on Plasma Science, 2021
High-energy ion beam emission above megaelectronvolts from the plasma focus strongly correlated with the transient impedance developed across the plasma column. Ion acceleration parameter is formulated based on the experimental ion spectrum coupled to the pinch simulation, to estimate the mean ion energy $E_{mn}$ from the accelerating potential

New mechanism for ion emission in plasma focus device

2007 16th IEEE International Pulsed Power Conference, 2007
A new mechanism for the acceleration and production of ions in Z-pinch discharges, especially plasma focus is presented. Previously, Yousefi et al. [Phys.Plasma 13, 114506 (2006)] studied the multiple compression and pinch mechanism; they reported that this event can be attributed to the (m=0) type instability, while the subsequent ion and neutron ...

X-Ray Spectra from Dense Plasma Focus Devices

The Physics of Fluids, 1970
X-ray spectra with energies up to 350 keV are reported for two paraboloidal plasma focus devices, the Mark I and Mark III device. Low energy x rays with energies between 5.46 and 29.2 keV were measured with Ross filters. Both time resolved and time integrated spectra were obtained.

Blue diode spectroscopy in a plasma focus device

The 31st IEEE International Conference on Plasma Science, 2004. ICOPS 2004. IEEE Conference Record - Abstracts., 2004
Summary form only given. The 405 nm blue diode has found many applications in medicine as a diagnostic tool for skin cancer. It has also been used to detect fluorescence from living plants, oils, paints etc. In this work, we report on the application of this laser as a diagnostic tool in a Plasma Focus Device (PFD).

Plasma Focus Device for Use in Space Propulsion

Fusion Technology, 1991
AbstractThe Plasma Focus at the University of Illinois will be used to study the potential use of a Dense Plasma Focus (DPF) for space propulsion. This will require the development of a DPF with a gas injection system. The ultimate goal is to measure the thrust from a gas-injected DPF fueled with D-3He.
