Latest Patents

One of Joel Le Fur's latest patents is a vacuum-tight window for microwave electron tubes and travelling wave tubes. This invention addresses the need for isolation of the vacuum region from external high-frequency input/output circuits. The design features a ceramic cylinder with metallic flexible rings at both ends, which is brazed to the cylindrical chamber under vacuum. This integration ensures that the chamber and window remain coaxial. The high-frequency transmission is facilitated by an antenna formed by a metallic strip mounted perpendicularly on a metallic cylinder that fits the chamber. This device is particularly applicable to power microwave tubes, especially travelling wave tubes.

Another significant patent involves a travelling wave tube equipped with an impervious coupling device. In this design, a microwave window extends between the coupling surface of a coupling pin and the end surface of a transmission line. This window is permeable to microwave energy while remaining impermeable to gases, ensuring a secure and efficient connection to the travelling wave tube.
