Positioning of the Precursor Gas Inlet in an Atmospheric Dielectric Barrier Reactor, and its Effect on the Quality of Deposited TiOx Thin Film Surface
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Thin film technology has become pervasive in many applications in recent years, but it remains difficult to select the best deposition technique. A further consideration is that, due to ecological demands, we are forced ...
High-Speed Monitoring of Dust Particles in ITER ELMs Simulation Experiments with QSPA Kh-50
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Dust generation under powerful plasma stream impacts has been studied in ITER ELM simulation experiments with QSPA Kh-50 plasma accelerator. Repetitive plasma exposures of tungsten have been performed by 0.25 ms plasma ...
Estimation of Amount of Scattered Neutrons at Devices PFZ and GIT-12 by MCNP Simulations
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Our work is dedicated to pinch effect occurring during current discharge in deuterium plasma, and our results are connected with two devices – plasma focus PFZ, situated in the Faculty of Electrical Engineering, CTU, Prague, ...
Long-Lived Plasma Process, Created by Impulse Discharge in Micro-Disperse Droplet Environment
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The processes of organic compound (phenol and cation-active surfactants) destruction in water solutions, which stay under the influence of plasma treatment have been investigated in different dynamic plasma-liquid systems ...
The Influence of Nitrogen in Ar+N2 Mixture on Parameters of High-Temperature Device with Electric Arc
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The paper presents the results of numerous experiments carried out on a high temperature device consisting of an arc heater with intensively blasted electric arc and reaction chambers connected to its output. The influence ...
Atmospheric Argon Free burning Arcs with a Simplified Unified Model Using CFD-Arc Modeling
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Free burning arcs, where the work piece acts as an anode, are frequently used for a number of applications. Our investigation is exclusively concerned with a simplified unified model of arcs and their electrodes under ...
Calculation of the Inductance of Plasma Column at PF-1000 Device with Assumed Current Distribution
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Processed data is taken from the D-D fusion reaction experiments on PF-1000 at IFPILM Warsaw, operating with 2 MA, 1011 neutron yield, using interferometry, temporal resolved neutron diagnostics, magnetic probe diagnostics ...
Velikhov Electrothermal Instability Cancellation by a Modification of Electrical Conductivity Value in a Streamer by Magnetic Confinement
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We present a method, confirmed experimentally, allowing the cancellation of Velikhov instability by operating a local magnetic field reduction along a lane, which enhances local electric conductivity and electron-gas ...
Materials for Fusion Applications
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
An overview of materials foreseen for use or already used in fusion devices is given. The operating conditions, material requirements and characteristics of candidate materials in several specific application segments are ...
Status and Perspectives of the Mini-MegaTORTORA Wide-field Monitoring System with High Temporal Resolution
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Here we briefly summarize our long-term experience of constructing and operating wide-field monitoring cameras with sub-second temporal resolution to look for optical components of GRBs, fast-moving satellites and meteors. ...
