Plasma Maintenance Mechanisms in Large-Volume Hollow Anode
Autor: I. V. Lopatin, Yu. D. Korolev, N. V. Landl, Olga V. Krysina, Oleg B. Frants, G. A. Argunov
Publikováno v: Russian Physics Journal. 63:1766-1772
The paper presents research into the low-pressure hollow-cathode and hollow-anode glow discharge. The data are obtained for the plasma potential, concentration and electron temperature in the hollow anode. The proposed model explains the plasma maint

Short Fluoride Cycle in Tungsten Technology
Autor: Yu. M. Korolev, A. N. Timofeev
Publikováno v: Russian Journal of Non-Ferrous Metals. 61:615-622
It is found that when a tungsten anode is electrochemically dissolved in a acidic fluorides of alkali metals (K,Na)H2F3 and hydrogen fluoride at a temperature of t ~ 37°C, the resulting atomic fluorine reacts completely with tungsten to form WF6. Th
