Eine kurze Vorstellung über uns und unser Institut.
Woher kommen wir?
Womit beschäftigen wir uns?
Additive Manufacturing (AM) has opened new frontiers in the fabrication of complex components for accelerator applications. However, the surface roughness of as-built parts remains a key challenge, particularly for high-frequency RF and vacuum environments. Plasma Electrolytic Polishing (PEP) is emerging as a promising post-processing technique to address this issue.
PEP is an...
To determine the relative permittivity $\epsilon_r$ and the dielectric loss factor $\tan(\delta)$ of 3D printed polymers at 500$\,$MHz a test cavity was built. When a dielectric material is inserted, the frequency and the quality factor of the cavity change. A comparison of the measured data with simulations yields the values of $\epsilon_r$ and $\tan(\delta)$. This allows the use of these 3D...
Besides beam characterization, cameras at our institute are also applied to acquire multipacting and cavity glowing effects during conditioning. To support these applications, additive manufacturing provides a fast, cost-effective, and flexible method for developing custom camera mounts precisely conformed to their specific positions, whether inside or outside a cavity.
In addition to its...
