Abstract：
Under different external electromagnetic fields,the electron densities of the electron cloud in a self-sustaining space-charge lens are measured with the radio-frequency method and the energy distributions of the ions produced in ionization are measured with the stopping field method.From them the relations between the focusing power of space-charge lenses and the external electromagnetic fields are determined.The available region of the Lebedev-Morozov formula is discussed.
