Relying on RAYSOV own independent accumulation in core technologies such as ultra-high vacuum acquisition, independent research and development of ceramics, high-frequency constant voltage technology, target material preparation and cathode electron beam modulation, RAYSOV Instrument Co., Ltd. has successfully overcome key technical challenges such as metal ceramic sealing process, small-sized anode heat dissipation design, and high-frequency constant voltage adaptation, and developed a metal ceramic X-ray tube suitable for high-frequency portable scenarios. Based on this core technology, it has launched a complete high-frequency portable X-ray flaw detectors.
