Considering the beam divergence and the convergence of the spherical electrode, the beam transmission model is presented, and the variation of beam edge is described by a formula, which is used to calculate the beam divergence half-angle with the experimental data obtained by the thermocouples. Assuming the beam divergence half-angle is constant in space and time, the beam profile distribution formula and variation of beam axial intensity are introduced. Taking the HT-7 Diagnostic Neutral Beam (DNB) as a reference, the divergence half-angle is calculated for the neutral beam shot 60901. The 1/e half-width of beam at collimation target calculated by formula is in agreement with that of experimental data. Variation of beam edge and axial intensity with downstream distance is estimated for HT-7 diagnostic neutral beam.
