Middle East Technical University – Defocusing Beam Line (METU-DBL) project is an irradiation facility providing 15 MeV to 30 MeV kinetic energy protons for testing various high radiation level applications, ranging from Hi-Lumi LHC upgrade, space electronic components to nuclear material research. The project located inside the premises of the TAEA (Turkish Atomic Energy Agency) SANAEM (Saraykoy Nuclear Education and Research Center) close to Ankara, provides users a wide selectable flux menu (105–1010 p/cm2/s). The facility is now being commissioned and the facility will be providing a large test area (20 cm x 15 cm) for material, detector and electronics tests. The proton beam is monitored along the beamline using aluminum oxide screens and the flux and uniformity is measured using three detectors attached to the robotic system for cross- checks. A fiber scintillator detector scans the large irradiation area while small area diamond detector and Timepix3 detector are used for spot checks for calibration. Several samples can be radiated simultaneously inside the irradiation area and the robotic system provides 5 separate holders for samples which can be moved in or out, providing users flexibility for the desired fluence. This talk will first introduce METU- DBL as a radiation test facility, then discuss the radiation monitoring of the beam area and the radiation room, while highlighting how this facility can be used for future testing of materials for radiation tolerance.

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...
METU-Defocusing beam line project and beam optics studies Demirköz, Melahat Bilge (2017-07-31) METU-Defocusing Beam Line (METU-DBL) project aims to perform Single Event Effect (SEE) tests for space, nuclear and medical applications. Turkish Atomic Energy Authority (TAEA) has a 30MeV proton cyclotron at Proton Accelerator Facility (PAF) mainly for radioisotope production and an R&D room for other applications. The proton beam current is variable between 0.1µA to 1.2mA and the beam size is small. METU-DBL, which is being installed in the R&D room, will enlarge the beam size with three quadrupole magnet...
PEM fuel cell degradation: numerical investigation and effects on the performance of solar-hydrogen based renewable energy systems Özden, Ender; Tarı, İlker; Department of Mechanical Engineering (2015) A hybrid (Solar-Hydrogen) renewable energy system consisting of Photovoltaic (PV) panels, Proton Exchange Membrane (PEM) fuel cells, PEM based electrolyzers and hydrogen storage has been investigated for a stand-alone application. A complete model of the hybrid renewable energy system has been developed using TRNSYS against a reference system, which was established for the emergency room of Keçiören Research and Training Hospital in Ankara. The main goal of the study is to verify that the system meets the e...
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...
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...
