METU Defocusing Beamline (DBL) is being installed at TAEA SANAEM Proton Accelerator Facility  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 . 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  and the ensuing irradiation campaign with different users . 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.
