AbstractMethods for control of the shell diameter, wall thickness and wall nonuniformity and also methods for selection of shells in fluid have been developed and investigated. The methods allow us to separate shells according to the diameter with 0.25 μ;m accuracy, to the wall nonuniformity with 5–7% accuracy, to make measurements of the diameter with 0.35 μ;m accuracy and wall thickness with 3–10%.These methods allowed us to develop the automated process cycle of control and selection of shells for laser fusion targets. A model automated line has been developed and joint operation of units has been investigated. The calculated automated line throughput during the shell analysis is 50–300 shells per hour, the control and selection accuracy for the diameter, thickness, and wall nonuniformity is 1%, 3–10% and 1–3%, respectively.Thus the foundations have been laid for an automated, high-quality target production technology for power stations based on laser fusion.

The article investigates the problem of providing high noise immunity radar under the influence of passive and intentional interference. The purpose of radio operation of the radar is to create conditions that would impede the operation of systems and minimize its effectiveness. The main method of radio transmission is still creating (staging) interference. Modern radar systems must solve the tasks in terms of electronic suppression using, including intentional interference and under severe time constraints. It is shown that the most effective way to improve the noise immunity of radar systems designed to operate in multipoint space, including non-stationary, interference is adaptive space-time processing of the received signals, based on the angular selection of targets, due to the formation of zeros in the directional diagram in the direction of interference sources. This problem is solved by determining the accuracy of the direction finding of interference sources and is achieved by the joint operation of the antenna array and multi-channel signal processing devices, namely the separation of interference signals on different receiving channels.

Automated line heating systems have been developed based on stand-alone operation with no consideration of the extensibility and maintainability. In the line heating shop, many of the line heating works are performed simultaneously; therefore, a collaborative and simultaneous automated line heating system is needed. In order to develop such a new line heating system, the current line heating process was analyzed, and then a distributed and automated process was determined, and the parts to be distributed and automated were identified to propose a distributed and automated line heating system based on modularization and network. Information and data flow from production design to robot control have been analyzed and integrated in the system. The system has two main processes: the calculation of the line heating information and execution of a working unit without calculation. A prototype of the system has been developed to study the feasibility of the system. Tests were carried out by using real production design data of a middle-sized Korean shipyard.

AbstractHollow foam spheres are needed for laser fusion experiments on the OMEGA laser facility at the University of Rochester as part of the demonstration of the feasibility of inertial confinement fusion. Previously polymer based foam and aerogel shells have been produced using resorcinol-formaldehyde (R/F) and divinylbenzene (DVB). In this paper we discuss the development of silica aerogel (SAG) shells. SAG may have the increased robustness, which is important in processing these laser targets. SAG shells were fabricated by the microencapsulation method using a triple orifice droplet generator. This technique allows for precise control of the shell diameter and wall thickness. Reduction of the aerogel gelation time is crucial to fabrication of intact shells with high yield. In addition, the proper choice of the components of the different phases of the microencapsulation process is essential for fabrication of intact SAG shells with proper sphericity and wall uniformity. The density of shells fabricated is approximately 100 mg/cc and the diameter ranges from 700–2000 μm, with a wall thickness of 50–200 μm. Development of a full density permeation barrier for retention of the fusion fuel will also be discussed.
