Complex Irradiation Facility (CIF)

Objective target

• Investigations about degradation of materials (solar sails, surfaces exerted to radiation) under simulated radiation conditions of space environment
• No organic compound materials (carbon hydroxide) for the design of CIF to avoid self-contamination (photo deposition effect)
• Complex irradiation with particles and electromagnetic radiation
• In-situ-measurement of the thermo-optical properties before and after the irradiation
