Hartree condition
WebThe Hull cut-off condition is described as the maximum range of the magnetron’s operation that can occur if an electron moves to the adjacent anode block with zero velocity in the radius of the anode and assuming that the electron motion moves towards the cathode, referring to the laws of energy conservation. The origin of the Hartree–Fock method dates back to the end of the 1920s, soon after the discovery of the Schrödinger equation in 1926. Douglas Hartree's methods were guided by some earlier, semi-empirical methods of the early 1920s (by E. Fues, R. B. Lindsay, and himself) set in the old quantum theory of Bohr. In the Bohr model of the atom, the energy of a state with principal quantum number n is given in a…

WebThe Hartree voltage UH is derived for a cylindrical magnetron in the relativistic limit with and without an axial current. This voltage corresponds to the breakdown voltage of the magnetron in the presence of a rotating perturbation field. In general, UH is less than the cutoff voltage UI for magnetic insulation in the absence of a perturbation field. … WebJun 4, 1998 · The Hartree voltage UH is derived for a cylindrical magnetron in the relativistic limit with and without an axial current.
