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 available to users starting in summer 2019. The final design has been updated with the experience gained from the pre-test setup installation [3] and the ensuing irradiation campaign with different users [4]. In this paper, magnetic measurement results of a custom design quadrupole magnet, as well as updates to the mechanical, robotic and control subsystems are presented.

Metu-Defocusing Beamline : A 15-30 Mev Proton Irradiation Facility and Beam Measurement System Demirköz, Melahat Bilge; Akanay, Avaroğlu; Besna, Bülbül; Pelin, Uslu; Erinç, Kılıç; Yusuf, Orhan; Selen, Akçelik; Merve, Yiğitoğlu; Çağlar, Saral; Uzun Duran, Selcen; Kılıç, Uğur; İlias, Efthymiopoulos; Anıl Berkay, Poyrazoğlu; Abdrahman, Albarodi; Nazire, Çelik (2020-01-01) 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/cm...
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 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...
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 ...
Non-contact atomic force microscope (ncafm) operation in uhv using radiation pressure excitation of cantilever Uysallı, Yiğit; Turan, Raşit; Yerci, Selçuk; Department of Physics (2016) In this work a new method for excitation of Non-Contact Atomic Force Microscope (NCAFM) cantilevers by means of radiation pressure was developed and applied for NCAFM imaging for the first time in the world. Piezo excitation is the most common method of cantilever excitation in AFM devices. However, it has few drawbacks, sometimes spurious resonance peaks and non-ideal Lorentzian curves can be observed. Radiation pressure has earlier been used for calibration of AFM cantilevers but has never been used for i...
