The Use of Direct Current in Induction Electron Accelerators

The application of a direct-current bias in the magnetic circuit of induction accelerators is described. In its simplest form this bias reduces power consumption to approximately 30 percent; in especially designed machines a reduction of the weight to 50 percent or less is an additional advantage. A machine with a closed central core is discussed and the use of orbit contraction by saturation over a range of x-ray energies is described.
