For unambiguous identification of products of nuclear reactions by the (TOF-DE) method, it is necessary to know exactly the magnetic field distributions, the 3D field map for the entire working area of separator. The possibility of the field reconstruction inside the total volume surrounded by the closed surface, on which the magnetic measurements are performed, is demonstrated in this paper. Distributions of the measured magnetic field components of the magnets, forming the magnetic structure of the separator, as well as the respective reconstructed fields together with the estimated reconstruction errors, are presented. Precise simulation of particle trajectories inside the separator becomes possible as a result of this work.
