  Determining the applicability of electronic components in spacecrafts involves conducting the tests using heavy ions. The Branch of URSC - ISDE and FLNR of JINR have created and operate the only in Russia test facilities based on the FLNR JINR accelerators allowing for heavy ion irradiation over a large area up to 200x200 mm. During simultaneous irradiation of several electronic components with heavy ions, it is necessary to ensure the device under test (DUT) location within the area of minimal nonuniformity. This problem is being solved by pretest determination of the irradiation field nonuniformity for each type of ion (Ne, Ar, Kr, Xe, Bi) and nonuniformity validation every 12 hours. Fluence is determined by a metrologically certified method using track detectors. In order to visualize the irradiation field nonuniformity, additional experiments were carried out with the irradiation of track detec-tors covering the entire irradiation area for each ion species. Based on the data obtained, a map of nonuniformity was plotted, which allows us to conclude that nonuniformity does not exceed 10% in the most frequently used areas of the irradiation field (100x150 mm) during SEE testing.
