Abstract
It is shown that the computational algorithms for calculating the region near the cathode and the expansion gap that are used in trajectory-analysis computer programs, do not match the accepted hydrodynamic-beam model or the conditions for emission in the ρ and T operation modes with zero initial velocity forming part of this model. As a consequence, the results of calculations of the beams with a high electron-beam compression of L ≥ 20 are invalid.
