Radiation damage to spacecraft is a major reason for malfunctions in electronic components. Monitoring real-time radiation that the spacecraft is exposed to is of utmost importance for subsequent investigation of faults and their correlation to radiation doses. Components which have completed mission lifetime successfully in space and therefore have gained heritage can be certified to a certain level of radiation tolerance for future missions. The design and optimization of a space radiation monitor was carried out as part of the IMECE project. The monitor consists of a proton radiation detector with heavy ion measurement capabilities, in a kinetic energyrange of 2 MeV to 200 MeV, in addition to an electron radiation monitor with a kinetic energy range from 100 keV to 7 MeV. Both are optimized to record hits in 8 energy bins and the electron one to record fluxes higher than those of protons by a factor of103for LEO flights. Utilization of degraders and silicon detectors in sandwich form is essential forthe working principal of the designed proton detector. Suitable readout electronics for these fluxes and flight qualification tests were chosen. This multipurpose radiation monitor will be manufactured and tested at the METU-DBL facility upon its completion. A prototypefor this radiation monitor was produced and flown to an altitude of 136 km twice on top the SR0.1 rocket launched by ROKETSANon the 26th -29th of October 2020. Dose rates weremeasured at the Pfotzer-Regener maximum as well as all through the flight path and are presented in this thesis.

Installation of the METU Defocusing Beamline to Perform Space Radiation Tests Demirköz, Melahat Bilge; Poyrazoglu, Anil Berkay; Seckin, Caner; Uslu, Pelin; Celik, Nazire; Bulbul, Besna; Albarodi, Abdulrahman; Akcelik, Selen; Orhan, Yusuf; Avaroglu, Akanay; Kilic, Erinc; Saral, Caglar; Duran, Selcen Uzun; Yigitoglu, Merve (2019-01-01) METU Defocusing Beamline (DBL) is being installed at TAEA SANAEM Proton Accelerator Facility [1] for radiation tests of electronic devices to be used in satellites and spacecrafts which are exposed to a high radiation dose in space or at the Hi-Lumi LHC [2]. 15 - 30 MeV protons from the accelerator are spread out over an area of 15.40 X 21.55 cm to provide large irradiation in accordance to ESA/ESCC No. 25100 standard with METU-DBL. A wide selectable flux menu ranging from 10(5) - 10(10) p/cm(2)/s will be a...
Design of an irradiation test facility for space applications Kızılören, Dilek; Demirköz, Melahat Bilge; Department of Physics (2014) 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 ass...
Space radiation environment and radiation hardness assurance tests of electronic components to be used in space missions Amutkan, Özge; Esendemir, Akif; Department of Physics (2010) Space radiation is significantly harmful to electronic Components. The operating time, duration and orbit of the space mission are affected by the characteristic of the radiation environment. The aging and the performance of the electronic components are modified by radiation. The performance of the space systems such as electronic units, sensors, power and power subsystem units, batteries, payload equipments, communication units, remote sensing instruments, data handling units, externally located units, an...
Development of a radioecological model for accidental release of radionuclides Unver, O.; Kocar, C.; Tuncel, G. (Carl Hanser Verlag, 2020-10-01) A dynamic radioecological model was developed to estimate radiation doses and stochastic health risks due to atmospheric releases in case of a nuclear reactor accident. Activities in some foodstuffs, feedstuffs and grass, and doses from different pathways for age groups and stochastic risks can be calculated by the model. Dynamic features include food harvesting, sowing times, feeding regimes, and the growing up of a person. The model can be coupled to any atmospheric dispersion model which can calculate ra...
Pretest Setup Installation of the METU-DBL Project to Perform Space Radiation Tests Demirköz, Melahat Bilge; Gencer, Ayşenur; Milanese, Attilio; Yigitoglu, Merve; Şahin, İlker; Baslar, Gamze Kilicerkan; Aydın, Murat; Uslu, Pelin; Duran, Selcen Uzun; Veske, Doga; Uzel, Ramazan; Bodur, Baran (2017-06-22) Satellites and spacecrafts are exposed to space radiation environment during their mission. This environment consists of cosmic rays, solar particles and trapped particles. Cosmic rays are coming fromthe outside of our solar system. Solar particles are produced by the Sun. These particles can be trapped around the Earth's magnetic field lines when they approach the Earth's atmosphere. These particles can affect performance and robustness of electronic components or materials used in space and such effects c...
