What Does HCD Stand For?

HCD stands for Hollow Cathode Discharge

Hollow Cathode Discharge (HCD) refers to a specialized plasma generation technique utilized in various applications, including material processing, surface treatment, and lighting. In HCD, a gas (typically inert) is ionized within a hollow cathode, creating a stable and efficient glow discharge. This process enables low-pressure operation and enhances the uniformity and control of plasma characteristics, making it ideal for applications such as thin-film deposition, plasma etching, and ion source development.
