Installation of the METU Defocusing Beamline to Perform Space Radiation Tests

摘要

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 × 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 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sup> - 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sup> p/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /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.
