Results of experiments aimed at the creation of ion sources employing alloys as materials for field emitters are presented. Using even simple alloys it is possible to obtain ion sources for elements, from which it is difficult or impossible to make emitter directly. Using emitter surface enrichment of some component it is possible to obtain an ion source even if the content of this element is as low...
In order to address the energy needs of tomorrow, powerline communication as one of the enabling technologies for smart grid is gaining a lot of momentum. In Particular, the U.S. distribution grid in the rural area is a great fit for powerline communication. In this paper we discuss the U.S. distribution grid topology and demonstrate how a PLC network can be deployed. We also show some field trial...
A mechanism of the erosion gap formation in a microsecond plasma opening switch at the end of the conduction phase is proposed. For the switch current, Is, linearly increasing at a rate Í, the voltage across the gap obeys the relation eVs / mc2 ∼ (u/c)2 or eVs / mc2 ∼ (u/c) for low or high switch voltage, respectively. Here, u=LÍ / 1s is the average velocity of magnetic field penetration into the...
The paper presents a review of continuing studies on production of S-band microwave pulses in a two-sectional single-mode vircator [1, 2] based on long-pulse (sub-microsecond) high-voltage generators. The two pulsers were used (a) generator with inductive energy store and fuse opening switch and (b) generator based on Marx bank and water forming line. The peak microwave output was on the range of...
