5 (in Lithuanian summaries in Lithuanian, English and Russian.). Any high voltage power supply that can produce over 10kV of potential difference will work. For decades, there was exactly one way to look at electronically displayed text and images: the cathode ray tube. If reuse or repair are not practical options, CRTs can be recycled. EPA encourages repair and reuse as a responsible ways to manage CRTs. Most modern cathode-ray oscillographs are provided with a saw tooth. Modern Cathode-Ray tubes are based on the theory that electrons in a vacuum tube can be gathered into a narrow beam which, upon striking a chemical coating at. The cathode ray tube/gas discharge tube does not require any sort of specialized power supply. A cathode ray tube (CRT) is the glass video display component of an electronic device (usually a television or computer monitor). Given method can be easily extended tohigher level aberrations modelling. tubes which have persistence of the order of 15 seconds. Demonstrated that paraxial approach to deflection aberrations appears as astigmatism. The proposed model is based on curvilinear optical axistheory. The cathode-ray tube of modern design, which today plays important roles in the fields of oscillography, radar, and television, made its appearance. Provided andsubstantiated the mathematical formulas required for aberrations modelling. Article analizes mathematical modelling aspects of modern deflection systems. Since the 1940s, there had been long-standing concerns about radiation leaks from black-and-white picture tubes. Despite theintensive development of new technologies, like liquid crystal displays (LCD) and plasma displays (PDP), it is obviousthat classic CRT will dominate in the market in many years to come.Due to large electron beam deflection angles δ > 45°, the application of conventional magnetic deflection systems aberrationstheory to modern CRT is not accurate. Color sets, the new technology of the time, were found to be radioactive. Rapid and continuous electronic industry development creates higher standarts for image reproduction devices, fromwhich cathode ray tubes (CRT) are currently most widely used, especially in reproduction of color images.
