Description

To include 3D printed polymer-based materials in accelerator parts the relative permittivity and the dielectric loss tangent of these materials have to be well known. A quarter wave cavity was built to measure these properties at a resonance frequency of 500 MHz by inserting a cylinder of the material under test, resulting in a frequency and quality factor shift of the cavity. By fitting the measured data to detailed CST simulations, the values of the relative permittivity and the dielectric loss tangent can be obtained. These results provide the necessary material parameters for further investigations into their use in RF accelerator components such as power couplers.
