Abstract：
The electron clouds in high vacuum which are confined by electromagnetic fields and sustained by thermionic emission are studied.The distributions of the electron density,the electron temperature,the drift angular velocity of electrons,the diffusion flow density of electrons and the electric potential in the electron cloud are discussed.
