The paper describes the results obtained from experimental operation of the arc heater with intensively blasted electric arc. The device has been designed for investigation of decomposition of stable harmful substances and later its construction has been modified to achieve steady operation with low gas flow rates. The modification consists in reduction the anode channel diameter with a solid cylinder...
The emission test is conducted using an easy-replaceable-emitter emitter test bench. A simple cylindrical button type emitter with the diameter of 6 mm is installed vertically into an emitter cup holder. The emitter is heated by a tungsten wire heater located around the cup holder. The emitter temperature is measured by an optical pyrometer at a given heater power. A high voltage pulse power supply...
High energy electron beams (30–150 keV) are widely used as intense heat source in welding, melting and evaporation of refractory metals. These operations are mostly carried out in high vacuum (10−4–10−5 mbar) to aid unimpeded flow of electrons from generation to the point of application. A 30 kV, 60 kW Electron beam optical column (EOC) is designed and developed under the high power beam technology...
Silicon power diodes can run into thermal destruction due to cosmic radiation-induced effects. We performed electro-thermal coupled device simulations in order to explain the failure mechanism. The results are compared to ion irradiation experiments. We find a strong heating located at the point where the incident ion deposits charge with a temperature rise which can explain melting of used materials.
The use of intense electron beams for ignition of pulsed thermonuclear reaction necessitates the investigations of interaction of beams having current densities of order 107A/cm2 and more, with metal foils. The present work is an extension of experiments on interaction of beams with thin foils having been started on Triton and Angara-1 [1, 2]. The most essential characteristics of the interaction...
