The Complex Irradiation Facility (CIF) is designed and commissioned with the aim to perform material investigations under radiation conditions as prevalent in space environment. Multiple radiation sources are combined to a vacuum irradiation chamber. Specimens can be exposed to a well-defined irradiation with protons, electrons, and electromagnetic radiation (IR, visible light, UV and VUV). The facility has is manufactured in UHV-technology with metal sealings and without organic compounds (rubber vacuum sealings, pump oil) to avoid self-contamination which could affect the results of the experiment.
Studies of material mechanical and thermo-optical properties change due to protons/electrons and electromagnetic radiation exposure.
