Space radiation can affect performance of electronic components during a satellite's mission. In order to ensure reliable performance, these components must be tested under some types of radiation. Middle East Technical University-Defocusing Beam Line (METU-DBL) project aims to perform Single Event Effect (SEE) tests for space, HiLumi LHC, nuclear and other applications. ESA ESCC No. 25100 Standard Single Event Effect Test Method and Guidelines is considered for these SEE tests. Turkish Atomic Energy Authority (TAEA) has a cyclotron which can accelerate protons up to 30 MeV kinetic energy at the Proton Accelerator Facility (PAF) mainly for radioisotope production and for R&D purposes. According to the standard, the proton beam kinetic energy must be between 20 MeV and 200 MeV. While the proton energy is suitable for SEE tests, the beam size must be 15.40 cm x 21.55 cm and the flux must be between 10(5) p/cm(2)/s to at least 10(8) p/cm(2)/s according to the standard. The beam size at the entrance of the R&D room is mm-sized and the current is variable between 10 mu A and 1.2 mA. Therefore, a defocusing beam line has been designed to enlarge the beam size and reduce the flux. The beam line has three quadrupole magnets to enlarge the beam size and collimators and scattering foils are used for flux reduction. Currently, METU-DBL preliminary test setup, which was installed in the R&D room, enlarges the beam size with only two quadrupole magnets and it reduces the proton flux with a collimator. The final beam size is about 6 cm x 8 cm and the beam flux is similar to 10(9) p/cm(2)/s. The first tests of electronic components were performed and the commissioning results from the beam measurement system are here presented.

Use of Al(2)O(3) layer as a dielectric in MOS based radiation sensors fabricated on a Si substrate YILMAZ, ERCAN; Dogan, Ilker; Turan, Raşit (Elsevier BV, 2008-11-01) The use of Al(2)O(3) dielectric in MOS based radiation sensors has been investigated. Their response has been compared with conventional MOS capacitors with a SiO(2) dielectric. The study includes gamma radiation effects with dose up to 4 Gy. The effect of radiation has been determined from the valance band shift in CV curves. The amount of charge induced by the radiation has been calculated and compared with the response of MOS capacitors with SiO(2) with the same and different thicknesses. Fading properti...
A study of cosmic ray secondaries induced by the Mir space station using AMS-01 Aguilar, M; et. al. (Elsevier BV, 2005-06-01) The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics experiment that will study cosmic rays in the similar to 100 MeV to 1 TeV range and will be installed on the International Space Station (ISS) for at least 3 years. A first version of AMS-02, AMS-01, flew aboard the space shuttle Discovery from June 2 to June 12, 1998, and collected 108 cosmic ray triggers. Part of the Mir space station was within the AMS-01 field of view during the four day Mir docking phase of this flight. We have ...
Impact of composition modification induced by ion beam Coulomb-drag effects on the nanoindentation hardness of HT9 Gigax, Jonathan G.; Kim, Hyosim; Aydoğan Güngör, Eda; Price, L. M.; Wang, X.; Maloy, S. A.; Garner, F. A.; Shao, L. (Elsevier BV, 2019-04-01) Accelerator-based ion irradiation is commonly used to simulate neutron damage, in lieu of neutron irradiation due to limited availability of fast flux facilities and little to no activation of the samples. Neutron atypical effects, however, must be recognized and their impact minimized in order to achieve the most accurate microstructural evolution under ion bombardment. Mechanical property changes, which arise from the synergy of numerous radiation-induced changes, are especially susceptible to these neutr...
Measurement of the jet radius and transverse momentum dependence of inclusive jet suppression in lead-lead collisions at root S-NN=2.76 TeV with the ATLAS detector Aad, G.; et. al. (Elsevier BV, 2013-02-26) Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at root S-NN = 2.76 TeV corresponding to an integrated luminosity of approximately 7 mu b(-1), ATLAS has measured jets with a calorimeter system over the pseudorapidity interval vertical bar eta vertical bar < 2.1 and over the transverse momentum range 38 < pT <210 GeV. Jets were reconstructed using the anti-k(t) algorithm with values fo...
