Preliminary Test Setup of the Metu Defocusing Beam Line, an Irradiation Test Facility in Turkey

METU-Defocusing Beam Line (METU-DBL) Project has been started in August 2015 and aims to construct a beam line at Turkish Atomic Energy Authority Sarayköy Nuclear Education and Research Center Proton Accelerator Facility to perform Single Event Effect (SEE) tests for the first time in Turkey. The METU-DBL is 8m-long and has quadrupole magnets to enlarge the beam size and collimators to reduce the flux. When complete the METU-DBL will provide a beam that is suitable according to ESA ESCC No. 25100 Single Event Effects Test Method and Guidelines standard. The METU-DBL beam size is 15.40cm x 21.55cm and the flux will be variable between 10⁵ p/cm²/s and 10¹⁰ p/cm²/s. The METU-DBL will serve space, particle, nuclear and medical physics communities starting from 2018 with performing irradiation tests. A preliminary test setup is being constructed towards first tests in March 2017. The beam size will be 6cm x 8cm and the flux will be 1.4x10⁹ p/cm²/s for preliminary test setup. The METU-DBL project construction status for the preliminary test setup is presented in this poster

Metu-Defocusing Beamline : A 15-30 Mev Proton Irradiation Facility and Beam Measurement System

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
