Özet:

Space radiation damages electronic components of spacecraft. Damages are due to cosmic rays which consist of protons, photons, electrons, and heavy nuclei. Function- ality and performance of the electronic components in flight depend on the orbital pa- rameters of spacecrafts and exposure time. The space radiation causes three types of effects and these are categorized as Single Event Effects (SEEs), Total Ionizing Dose (TID) Effects and Non-Ionizing Dose Displacement Damage Effects. Radiation hard- ness assurance tests have to be conducted to ensure performance and functionality during operational lifetime of spacecraft. SEE radiation tests are planned to be carried out using a 30 MeV beam line in the Research and Development room of Turkish Atomic Energy Agency (TAEK) at Sarayköy Nuclear Research and Training Center (SANAEM). A reduction of the flux and an enlargement of the target irradiation area are necessary to perform tests accord- ing to ESA Standards. Collimator and thin films are planned to be used to expand the beam line and reduce the flux. The simulation of beam line design is carried out using FLUKA and MADX. The first SEEs radiation test in Turkey is foreseen to be carried out using this beam line.
