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, and propulsion subsystem units is determined by the properly functioning of various electronic systems. Such systems are highly sensitive against space radiation. The space radiation can cause damage to electronic components or functional failure on the electronics. A precisely methodology is needed to ensure that space radiation is not a threat on the functionality and performance of the electronics during their operational lives. This methodology is called as ”Radiation Hardness Assurance”. In this thesis, the hardening of electronics against space radiation is discussed. This thesis describes the space radiation environments, physical mechanisms, effects of space radiation, models of the space radiation environment, simulation of the Total Ionizing Dose, and ”Radiation Hardness Assurance” which covers Total Ionizing Dose and Single Event Effects testing and analyzing of the electronics.

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...
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...
Design of a space radiation monitor for a spacecraft in leoand results from a prototype on the first Turkish sounding rocket Albarodi, Abdulrahman; Demirköz, Melahat Bilge; Department of Physics (2021-2-03) 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 ...
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...
Investigating Glow Discharge Detectors as a Millimeter-Wave/Terahertz Radiation Detection Tool Alasgarzade, N.; Nebioglu, M. A.; Takan, T.; Uzun Kaymak, İlker Ümit; Şahin, Asaf Behzat ; Altan, Hakan (2015-11-05) Compared to other forms of electromagnetic radiation, Terahertz (THz) radiation is considered safe for imaging and detection purposes due to their non-invasive and non-destructive nature. Novel techniques and methods are constantly being evaluated for efficient detection and measurements of THz waves, yet their commercial success is limited due to cost and overall complexity of these systems. Commercially available Glow Discharge Detectors (GDDs) are proven to detect microwave and higher frequency radiation...
