Triple Probe Measurements in Transient Plasma of Pulsed Capacitive Discharge
Springer Science and Business Media LLC - Tập 34 - Trang 405-410 - 2014
A. Qayyum, S. Ahmad, N. Ahmad, Farah Deeba, S. Hussain
Triple Langmuir probe (TLP) technique is used to measure local and time-resolved plasma parameters in pulsed capacitive discharge. This technique allows the instantaneous measurement of plasma parameters in transient discharges and obviates the need of any voltage or frequency sweep. In TLP configuration, two probes are differentially biased to acquire ion-saturation current whereas third probe is...... hiện toàn bộ

Investigation of fusion reactions in palladium and titanium tritide using galvanostatic, coulometric, and hydrogen permeation techniques
Springer Science and Business Media LLC - Tập 9 - Trang 299-304 - 1990
T. R. Guilinger, M. J. Kelly, J. R. Scully, T. M. Christensen, D. Ingersoll, J. A. Knapp, R. I. Ewing, W. H. Casey, S. S. Tsao
We describe several electrochemical methods used to investigate the possibility of cold fusion phenomena in palladium and titanium tritide cathodes. We performed long-term (up to 77 days) electrolysis experiments with electrochemical cells of the University of Utah type at current densities as high as 1 A/cm2, while monitoring neutron and tritium levels. With some cells, we pulsed the current to d...... hiện toàn bộ
Comparison of Investment and Related Requirements for Selected Hydrogen Vehicle System Pathways
Springer Science and Business Media LLC - Tập 21 - Trang 181-191 - 2002
S. Locke Bogart
A model was developed for production, transmission, delivery, and consumption of hydrogen for large-scale systems ultimately providing shaft-work for hydrogen-based vehicles. (See Glossary, after References). Presently, the supply technologies are limited to solar photovoltaic, wind, nuclear, and nuclear thermochemical sources. Transmission technologies include electric power, hydrogen pipeline, a...... hiện toàn bộ
Taming the Heat Flux Problem: Advanced Divertors Towards Fusion Power
Springer Science and Business Media LLC - Tập 35 Số 1 - Trang 27-30 - 2016
Kotschenreuther, M., Mahajan, S., Valanju, P. M., Covele, B., Waelbroeck, F. L., Canik, J. M., LaBombard, B.
The next generation fusion machines are likely to face enormous heat exhaust problems. In addition to summarizing major issues and physical processes connected with these problems, we discuss how advanced divertors, obtained by modifying the local geometry, may yield workable solutions. We also point out that: (1) the initial interpretation of recent experiments show that the advantages, predicted...... hiện toàn bộ
Calculation of Beam Extraction Pulse Duration for Beam Angular Divergence Measurement of EAST Neutral Beam Injection
Springer Science and Business Media LLC - Tập 29 - Trang 395-398 - 2010
Yongjian Xu, Chundong Hu, Yuanlai Xie, Qiang Guo, Ling Tao
Distributed thermocouple measurement will be used on EAST neutral beam injection beam angular divergence measurement. In order to determine the pulse duration of neutral beam extraction, the plates of calorimeter are analyzed by using heat transfer science. Mathematic derivations and the results are given according to the installation location of thermocouple in the plate. Those results could poin...... hiện toàn bộ
Study of Some Structural Fusion Materials for (n,2n) Reactions
Springer Science and Business Media LLC - Tập 34 - Trang 746-750 - 2015
Tarik S. Reshid
Studies of (n,2n) reaction are especially important for neutron multiplication. The (n,2n) cross section is neutron multiplier reaction in fusion reactor design. 27Al, 51V, 52Cr, 55Mn, 56Fe and 58Ni nuclei are the some structural fusion materials. Therefore, (n,2n) reactions of the selected blanket materials can play a key role for multiplying neutrons in reactor environment. In this study, for so...... hiện toàn bộ
Current Sharing Analysis of External Bypass for ITER Poloidal Field Converter
Springer Science and Business Media LLC - Tập 34 - Trang 225-231 - 2014
Peng Wang, Zhiquan Song, Peng Fu, Jinchao Li, Chuan Li, Lin Dong, Min Wang, Tongzhen Fan
The current sharing of bridge arm is very important for the design of external bypass, which provides protection for the ITER poloidal field converter and magnets in fault conditions. Thyristors in parallel should withstand short peak current for each arms. In this paper, the method based on inductance matrix is presented. After theoretical analysis and simulation, the prototype has been manufactu...... hiện toàn bộ
Investigation of Nitrogen Soft X-ray Emission from Dense Plasma Focus with Anode with Curved Tip Using the Lee Model
Springer Science and Business Media LLC - Tập 42 - Trang 1-7 - 2022
Hadi Barati
The Lee model has been employed to investigate the nitrogen soft x-ray emission from a Mather-type dense plasma focus device with an elliptical anode head. The simulations have been performed for various values for the minor radius of the elliptical anode head. These values have been presented as a factor of the anode radius, i.e. ...... hiện toàn bộ
