Barkhausen–Kurz tube

The Barkhausen–Kurz tube is a type of vacuum tube that was developed for the generation of high-frequency oscillations. It is named after its inventors, Heinrich Barkhausen and Karl Kurz, who contributed to its development in the early 20th century. The Barkhausen–Kurz tube is essentially a form of oscillator that utilizes the principles of electron dynamics in a vacuum environment. The design typically involves a cathode that emits electrons, which are then accelerated toward an anode.
