Nuclear fusion is fundamentally a reaction in which light atomic nuclei combine under extreme temperatures and pressures to form heavier nuclei, releasing vast amounts of energy.

In the evolution of microwave technology, the magnetron has played a pivotal role. Among its various types, the continuous wave (CW) magnetron stands out as a crucial component due to its ability to deliver stable, continuous microwave energy over extended periods.

As a core device capable of efficiently generating microwave energy, the magnetron has continuously shattered boundaries in energy applications since its inception.

Diamond, the hardest material in nature, is rapidly expanding into high-end fields such as semiconductor thermal management, power electronics, quantum technologies, and optical devices.

​In the power equipment system, the vacuum Interrupter, as the core component of the vacuum switch, plays an important role in connecting, carrying, and breaking current.

​GLVAC ceramic vacuum capacitors have been widely used in modern high-end manufacturing equipment due to their unique performance advantages.

Currently, the low-altitude economy is experiencing vigorous development, and low-altitude passenger transport is undoubtedly one of its most valuable applications.
