METU-Defocusing Beam Line (METU-DBL) project aims to perform Single Event Effect (SEE) tests for space, nuclear and other applications. 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 research and development (R&D) purposes. In the facility, the stable proton beam current is variable between 0.1 µA to 1.2 mA and the beam size is nearly 1 cm x 1 cm. METU-DBL pre-test setup, which has been installed in the R&D room, enlarges the beam size with two quadrupole magnets and it reduces the proton flux with a collimator. The pretest setup beam size is about 10 cm x 10 cm and the beam flux is 108 p/cm2/s. The first tests of electronic cards, detectors and also commercial and experimental solar cells have been performed using this setup. Also, the final configuration of METU-DBL is now under construction to provide a beam according to ESA ESCC No. 25100 standard. MCNP Monte Carlo codes were used for the calculations of secondary particles (neutrons, gammas) and residuals.
