Electronic components must be tested to ensure reliable performance in high radiation environments such as Hi-Limu LHC and space. We propose a defocusing beam line to perform proton irradiation tests in Turkey. The Turkish Atomic Energy Authority SANAEM Proton Accelerator Facility was inaugurated in May 2012 for radioisotope production. The facility has also an R&D room for research purposes. The accelerator produces protons with 30 MeV kinetic energy and the beam current is variable between 10 mu A and 1.2 mA. The beam kinetic energy is suitable for irradiation tests, however the beam current is high and therefore the flux must be lowered. We plan to build a defocusing beam line (DBL) in order to enlarge the beam size, reduce the flux to match the required specifications for the irradiation tests. Current design includes the beam transport and the final focusing magnets to blow up the beam. Scattering foils and a collimator is placed for the reduction of the beam flux. The DBL is designed to provide fluxes between 10(7) p/cm(2)/s and 10(9) p/cm(2)/s for performing irradiation tests in an area of 15.4 cm x 21.5 cm. The facility will be the first irradiation facility of its kind in Turkey. (C) 2015 The Authors. Published by Elsevier B.V.

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...
Proton irradiation and gamma-ray irradiation testing studies on the commercial grade GaNFETs to investigate their characteristics under the space radiation environment
Boyacı, Lütfi; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019)
In this thesis, the radiation performances of the commercial GaNFETs were investigated for the possible future integration of these devices to the power subsystems of the satellites as a main switching power element instead of the Silicon MOSFET. Two main irradiation tests were applied to the GaNFETs, namely proton irradiation test, and gamma-ray irradiation test. By these tests, tough space radiation environment was simulated to understand the GaNFET’s radiation performances. In the proton irradiation test...
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 ...
Pretest Setup Installation of the METU-DBL Project to Perform Space Radiation Tests

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...
Radiation effect studies on partially crystalline bulk amorphous Fe-based metallic glass
Kiceci, Pelin Uslu; Akdeniz, Mahmut Vedat; Demirköz, Melahat Bilge; Mehrabov, Amdulla (2022-02-01)
The selection of appropriate materials for radiation environments is critical due to the harsh and aggressive conditions found in such environments, which are liable to degrade material properties. Therefore, durability of materials should be tested before being deployed. In this respect, proton tests are required for the materials to be used in the space environment because dominant galactic cosmic rays mostly comprised high energy protons. Bulk metallic glasses are candidate for space environment due to t...
