TL;DR: In this article, the results of pulsed X-ray radiography of an electron beam spot on the anode of a diode employing an explosive-emission cathode were presented.
Abstract: We present the results of pulsed X-ray radiography of an electron beam spot on the anode of a diode employing an explosive-emission cathode. It is demonstrated that this technique can provide objective information on the character of emissive centers on the cathode surface and can be used for preliminary evaluation of the possibility of using a particular explosive-emission cathode type for the formation of desired electron beams in a given diode.

TL;DR: In this paper, the results of simulation of Raman optical amplifiers with copropagating and counterpropagating pumping were presented for various applications of optical amplifier allowing to increase regenerator section length.
Abstract: The paper contains the results of simulation of Raman optical amplifiers with copropagating and counterpropagating pumping. The computer program was developed to calculate signals and noise of amplified spontaneous emission for various lengths of amplifier sections. The various applications of optical amplifiers allowing to increase regenerator section length are considered. The results of calculations are of interest to the designers of long-haul fiber-optic communication systems.
