A study is made of utilizing electron trapping in dielectrics as a means of synchronous altitude. Traps retain electrons, and large internal electric fields are induced within the dielectric. Electrons penetrating the insulating material can lose most of their kinetic energy to the electric field with a subsequent decrease in energy loss to bremsstrahlung. This acts to reduce bremsstrahlung production. It also lowers the average radiation energy of that which is produced. A thin layer of dielectric material on the external surface of a spacecraft should provide an effective, light and inexpensive shield against bremsstrahlung.
