This invention includes two alternative advanced methods to achieve a homogenous collector power distribution, which improves the collector capability of high power vacuum-tubes by a factor of two as compared to conventional methods. Furthermore the applied method has a high flexibility to vary the power distribution over a wide range of profiles and match the deposition profiles to different designs of collectors in existing or future electron tubes.

The invention presents a high-precision rotation holder designed for optical components such as polarization filters. This innovative device features a rotor with an axial hollow shaft and an air-bearing system for frictionless rotation. Driven by an airflow turbine, the holder incorporates an angle encoder for precise measurement of the rotational position. Key applications include polarimetry in the terahertz spectrum, enabling advanced analysis of electromagnetic radiation. The invention ensures ...

This invention presents a method and apparatus for investigating the hydrogen permeability of materials, offering a simplified and cost-effective solution to test the tightness of a material. A sensor is placed on one side of the test object, while a hydrogen-containing test gas is applied to the opposite side. The hydrogen permeating through the material interacts with a sensitive sensor layer, causing measurable physical changes such as color shifts. These changes provide real-time, spatially ...

The invention enables a fast and effective safety for persons (or obstacles) being in danger of hitting the beam of powerful lasers like YAG lasers. While being extremely powerful, the YAG laser light is invisible to the human eye. The safety mechanism is based on a harmless, visible laser light, i.e., cylindrically surrounding the YAG beam a shutter mechanism (i.e., with an entrance of cylindrical symmetry and made of synthetic material). The safety laser light is controlled by a ring (or sector) ...
