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 ...

Plasma dynamics from a two-gun plasma focus device

IEEE International Conference on Plasma Science, 2003
The Mather-type two-gun plasma focus device has a pair of cylindrical electrodes connected head to head. Their separation can be altered, whereas the electrode length remains unchanged. This feature allows for the study of the interaction between two plasma foci at the same operational parameters (1520 mu F, 19 kV).

An investigation of the plasma behaviour in a Filippov type plasma focus device

Plasma Physics and Controlled Fusion, 2007
Plasma behaviour in the 90 kJ Filippov type plasma focus (PF) device Dena, is studied both experimentally and theoretically. The latest experimental data obtained by the use of the Dena facility are presented. Then the experimental data are compared with the simulated data obtained through the ML model.

Plasma sheath dynamics on the axial phase of a plasma focus device

2016 IEEE International Conference on Plasma Science (ICOPS), 2016
Results on coordinated experiments and MHD simulations on the axial phase sheath dynamics of dense plasma focus are presented. The aim of this effort is to use a repetitively fired dense plasma focus (DPF) to gather data from 100's to 1000's of shots per gas load, so as to better refine numerical codes.

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).

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.

Application of Plasma Focus Device to Compression of Toroidal Plasma

Japanese Journal of Applied Physics, 1980
A new concept of compressing a toroidal plasma using a plasma focus device is considered. Maximum compression ratio of toroidal plasma is determined merely by the initial density ratio of the toroidal plasma to a sheet plasma in a focus device because of the Rayleigh-Taylor instability, An initiation senario of plasma-liner is also proposed with a ...

Operation of a plasma-focus device with D2 and He3

Journal of Applied Physics, 1977
Two plasma-focus devices at the Lawrence Livermore Laboratory, the B Division device (BDPF), with a stored energy of 73 kJ at 18 kV, and the Physics Department device (PDPF), with a stored energy of 67 kJ at 20 kV, were operated with various mixtures of D2 and He3. The purpose of the experiments was to evaluate the D-D/D-He3 yield ratio as a diagnostic
