It is proposed that the conventional electron microtron may be converted into a high-energy accelerator for protons or electrons in the Bev range, and capable of very high currents. It would require a high-energy injector, e.g., an FFAG cyclotron, capable of supplying protons of energy above 500 Mev in a beam of high intensity and high quality. The changes required are the introduction of Thomas focusing (sector fields). the use of linacs for acceleration, and the use of high-energy injection. The resulting accelerator uses fixed (and sometimes even uniform) magnetic fields, a fixed frequency r-f accelerating system with wavelength near 20 cm. and may be designed in one stage or in a cascade of two or more stages, each using a separate linac, with contiguous fields. It is capable of reaching arbitrarily high energies without betatron resonance difficulties, it possesses phase stability, and it provides a beam, remarkably homogeneous in energy, which may he easily and completely extracted from the machine, since successive orbits are well separated. The problems of orbit dynamics, linac design, betatron and phase oscillations, and cascade operation are discussed, and sample designs for a 3-Bev proton accelerator are given. The theory of synchronism in nonzero-gradient fields is presented. An analytic theory of phase oscillation is given. The name ''auxinotron'' is proposed for the new type of accelerator. (auth)
