Present Status of Research

Brief Description of Research

Original technologies have been developed: — production of foils of (40-100) m in thickness made of single tungsten, molybdenum crystals and their alloys with niobium, rhenium and tantalum; — production of high-voltage insulators made of single-crystal alumina (leucosapphire); — production of dead joints of insulators with metals; — production of vacuum devices, in particular X-ray tubes with metal-ceramic units.

Project aim: development of high-intensive impulse source of X-radiation based on these technologies.

The novelty of this proposal lies in that for the first time in the practice of vacuum device production are used single-crystal refractory materials (metals and ceramics) which have the unique properties of high purity, dimensional stability under conditions of high-intensive electronic action, density close to the theoretical density, as well as increased mechanical and thermophysical properties. These properties provide increase in service life and intensity of X-radiation with stable electric characteristics.

Using of single-crystal materials and new original technologies will allow to make an impulse source of X-radiation with increased service life and increased intensity of X-radiation.
